First, thank you for your help.
I redo everything from scratch and same problem.

The return from your php function is : "www26@celeonet.fr/home/www/XXX/www"

My hoster is Celeonet and my XXX is my login (to my MySQL database and admin hoster panel).
In my root directory I have a "www" directory where I upload my site.
My zenphoto galerie is then in a sub-directorie called "galeries".

I've noticed again than I cannot setup my login and password directely because I have this at the en of the process :
http://grab.by/9Ght
then this after I've clicked on the delete setup files button :
http://grab.by/9Ghs
the I refresh and I get this :
http://grab.by/9Ghn
Anf finally I can see the admin panel who says that I can connect to admin (I enter no password nor login ID) and I've got this :
http://grab.by/9GhL

I don't know if it helps but I'v got this at the end of the process install :
http://grab.by/9GiJ

I don't know if these unusal behavior at the end of the install process (whith no error message I must say) could help to understand why then I have time to time these"setup scripts missing" error message.

Thanks

If I understand correctly, you apparently have five different WEB addresses (The 9Gxx items) for your install. This is highly unusual and will simply not work for Zenphoto.

Given your description of the installation, the site should be addressed by something like yourdomain.com/galleries. As to why this would be--that is a question for you to ask the Celeonet support team.

No the 9Gxx adresses are just adresses to host my screen captures (I'm using tinygrab services with no link to zenphoto ... just a screencapture hoster).

By the way : I run Zenphoto on my MAMP local server with no problem and another Zenphoto site on another hoster with no problem (and with my own personnal themes).

That's why I'm just wondering what's hapening and I have no clue !

My only adress for my site is http://www.atelierscales.net and the zenphoto index is at http://www.atelierscales.net/galeries
(there is no pictures at the moment and so you can have either a "normal" website page or the famous "setup scripts missing" message).
Any idea abiyt the "return" I've got about the function acryllian suggest to insert to me to see what's the retrun ?

Many thanks.

Well, first there were two items acrylin asked you to echo. You reported just one. But that is not so relevant at the moment. What we need to see is what those elements are both when the site runs correctly and when it diverts you to the setup files.

But more to the point. The erratic of the site would tend to point to a problem with the Database. You should ask your service provider for help here. They should be able to review their server logs to find out what is happening.

Thanks again for your help.

Actuallty I have for $_SERVER['SERVER_ADMIN']
www223@celeonet.fr
And for
/home/www/damino/www

I send an email to my hoster and I'm wainting for answers.

I've seen that my memory_limit on the php.ini is 16M.
Do you think this can explain some of my problems ? Or other php.ini parameters ?
I'm just crazy and I re-install form scratch many times with no improve.
In the setup_log file I've seen that the cookie test of the installation failed.

Could be that there is not enough memory to successfully run MySQL. The eratic behavior really points to database issues.

Hi, my hoster find no problem with the database and give me for free and to try more memory_limit.
But no way, still the "erratic" running zenphoto.

The strange thing is that I have no problem on the same database with a Wordpress installation.
And no problem with Zenphoto on other hoster.
One more question : when the message error says "setup scripts missing" : which files are we talong about and what is the process that normaly brings to this message.

Probably an incompatibility with Zenphoto and one of the parameters of Celeonet (should something in the php.ini or somewhere else with the server functions could brings this message ?)

Thanks.

You get that error, when, well, the setup scripts are missing. That is either the case that Zenphoto is not installed correctly because some files have not been uploaded.

Or you deleted these files after installing as setup suggest after completion and also provides a link to.

If I uplaod again the setup.php, setup_set-mod_rewrite.php and all the files whithin the setup directory and I run the install process as if ti was an update I've notice this message (it is a translation form French to english :

Quote:Some basic files of Zenphoto are missing or their modification date doesn't match
Attention !

A problem may have occurs during the upload to the server? You shoul check les followin files :
zp-core/setup.php
zp-core/setup_set-mod_rewrite.php
zp-core/setup/setup-functions.php
zp-core/setup/setup-option-defaults.php
zp-core/setup/setup-primitive.php
zp-core/setup/setup-sqlform.php
zp-core/setup/setup.css
zp-core/setup/setup_permissions_changer.php
zp-core/setup/setup_themeOptions.php
If I check I have all these files on my server but may it's a begining of a solution ... I hope ...

This is just a warning about the file times as you uploaded them later as the others. I think you can just proceed.

OK I thought this.

My hoster just says me :

Quote:If you study the source code about your error message (available here : http://www.zenphoto.org/trac/attachment/ticket/1776/index.php), you can see that this message is due to the absence of some files that Zenphoto needs to run properly
You should check your installation.
Are we agree he's wrong ? No files are missing.
That also why I thing it's more a bad interaction in beetwen the hoster and a Zenphto (as other sripts runs on these hoster and as i run other zenphoto on other hoster).
Anyway, if files were really missing I thing that it should works or NOT but not works time to time. Am I right ?

Thanks again and if I can't find solution I will move my zenphoto to another hoster.

But finally this is something that could be interresting to underdant because it suppose that Zenphoto needs to checks some points to be sure it will run on an hoster (once again other scripts like Wordpress runs with no problem on this hoster with the same database).

So what is the actual issue now? You got an error about setup files missing, uploaded them and then got a warning about the file times which is okay in this case.

So what happens if you proceed with setup?

No, I still have the same error "setup scripts missing" after I install Zenphoto and even if I re-install from scratch or just re-upload the setup files and run the script : the site runs but sometimes not.

I'm stuck.

Do I understand correctly? You make a complete upload of the Zenphoto files and then run the install. Then [b]without your deleting the files[/b] you get the setup scripts missing error?

That indeed would be a strange situation. Have you used FTP to check if the scripts are there after this message? If not, then someone has deleted them. If they are present, then there is some issue on your site with PHP scripts being able to read files and folders. That is a reasonable possibility because sometimes the Security Police of a site are over zealous.

Applications such as Wordpress are not filesystem based so they would not notice such a server defect.

Hi.

Actually I think something went wrong during the installation even if I have no critical error message during this process.

1-I restart from scratch :
2-On the install information page, it says that I have to fill the information databade.
3-I do this and I save then the page refreshes and I click on the "Go" button at the buttom of the page.
4-After that, another window suggests me to delete setup files (button). In the same window a link says to me to define administrator login and password and nothing else (there is no input fields to define login and password).
5-So I clicked on the button to delete setup files.
I checked on my server with FTP and the files are effectively deleted.
6-Then an almost blanck page with just Zenphoto logo, a drop list with language and all the links to zenphoto website at the bottom and just a link which says again "you have to define administrator login and password". No input fields here.
7-I clicked on the link to setup my administrator login and password.
8-Problems begins here 2 options : error message or I land on the galerie index page.
9-From the galerie page I can see the Admin Toolbox (at the top right) and if I click on it (Administrate) I land on a backofffice page which says in red : "ask for resting of the password. You have to specify now the login and password of administrator".
10-I do this and then I have the erratic running zenphoto : sometimes OK sometines not.

Sorry for my translations and my english.

Ok. I still think this is a problem with your database. Most likely it is not responding back within the timelimits of the server script timeout.

I had the same problem, i was not able to verify where it happenend or how. how ever everthing seems to work fine when I change functions.php checkInstall() to just return false

So it means that you skip the test function to avoid the message.
How do you do ? And doesn't it bring some trouble when you'll update your Zenphoto ?

I just changed the code to

function checkInstall() {
return false;
.....

and yes it will not work when upgrading.

However I do suspect that this is a bug in the upgrade process and next time i upgrade the bug won't be there (or I play by the rules and only upgrade one version at the time)
