after upgrading to 1.4.1 using latest release with fixed bug i get redirected to login screen when trying to access admin.
any ideas on how to solve this?

Did you try everything that has been discussed on the forum?

Probably you should also describe your setup--specially anything that might not be "standard" stuff. There are a few users having this problem, but since we cannot reproduce it and there no particular configuration descriptions exist, we have no guess as to the problem.

Maybe if everyone having the problem would describe in detail their configurations something would stand out.

i have a standard installasjon on my domain. use the zenpage plugin, and the zpGalleriffic v1.4 theme. other than that no other plugins other than included in release installed. 1 user who is admin (me) no need for users to log in on frontpage. Frontend of system works perfectly, only the backend that somehow is screwed up. My zenphoto installation worked perfectly on all previous versions but after upgrading to lates zenphoto version everything went bad.

Its tempting to cleanout everything and do a fresh install but then i loose years of data, comments etc

Is this enough info or how do i describe by installation in better detail? Any ideas on stuff to try?

Well, the version of Zenphto (in the brackets) would help.
Also your server configuration. PHP version, MySql version, etc.
What options have you chosen? Things like secure-admin, mod_rewrite, etc. that impact how the site runs as opposed to theme configuration options.

Everyone having this difficulty please try the nightly build of 29 June. Report if fixed or not.

I tried the nightly build of 29 June on different installs.
I'll describe in some shorthand way what I did.
Hope this all makes some sense.

click "backup/restore" -> restore database with previous backup (any backup seems to work) -> click admin tab -> login form -> success, everything works.

So in short words the fix in the nightly did work?..:-)

LOL ;-)

Sadly I have the same problem and have tried the fixes noted above but to no avail. The admin login just keeps redirecting me back to the login page.

If I enter what I believe to be the correct user and password combination it returns me to the login page.

If I enter a known bad password it loops back to the login page but includes the warning message: "There was an error logging in. Check your username and password and try again."

Entering the username to request a password reset works - the email message is sent, I log in and change the password, am redirected to the login page and the problem repeats itself.

A new install using the latest nightly build (June 29) didn't fix it, although the setup accepted the admin username and password correctly during the update.

Dropping the administrators table and re-running setup created a new table and entries but the problem still persists.

Sadly I still can't help nor reproduce the issue. You have to wait until my collegue is here later today.

Same for me.

What I have noticed is that I can still log in from one of my macs on a different IP address. (wi-fi connection), but when i try to log in on my laptop (mobile internet) it redirects.

I have dropped tables, re-installed, cleared cookies, followed all possible suggestions, but I am still being redirected. Also installed latest nightly build.

Also very interesting, all the login attempts that are redirected back to the login page, are seen as successful login attempts in the security log.

I have a debug log which I can email if that would help.

Mike

Please make a ticket and attach the log.

Zenphoto cookies are "tied" to the IP address. Maybe the mobile connection does not maintain a consistent IP?

For anyone still having the redirect issue please make the following change to the `functions.php script`:

change
`
function zp_cookieEncode($value) {
return rc4(getUserIP().HASH_SEED,$value);
}
`
to

`
function zp_cookieEncode($value) {
return $value;
}
`
circa line 1709 of the file. Please report the results.

P.S. Ticket created and two logs (from yesterday) attached.

Can you detail the shared host situation? The debug log does not show any "save" of the new admin. (Really do not know what the SQL timeout was, but probably not related.)

You state that one attempt was previously logged in and the other not. But the log does not contain any administrators, so I guess I do not understand.

Also, if you re-create this, please get to the setup screen which will redirect you to the set admin page and then delete the debug log so it has only the relevant data.

My apologies for the delay. The grass-cuttimg was calling and it's a beautiful evening here in Ireland!

M. Sbillard - your patch resolved the problem for me. Thank you.

Do you still need me to submit a ticket and attach the log?

Mike

Spoke too soon.

Am logged in ok but when I try to edit an album I receive the following error message:

Division by zero in /home/bpskdk/public_html/zenphoto/zp-core/admin-edit.php on line 993
