I installed Zenphoto via my hosting company a while ago and everything has been fine, until now.

When I view an album I get the following error message.

ZENPHOTO HAS DETECTED A CHANGE IN YOUR INSTALLATION.
Your server software has changed from Apache/2.4.6 (Unix) to Apache/2.4.6 (Unix).
Please reinstall the following setup files from the 1.4.4.5 [578af0f46b] release:

zp-core/setup/index.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_permissions_changer.php
zp-core/setup/setup_pluginOptions.php
zp-core/setup/setup_set-mod_rewrite.php
zp-core/setup/setup_themeOptions.php
The change detected may not be critical but you should run setup at your earliest convenience.

Can anyone give me an idea of what is wrong and how to fix it please.

Please see: http://www.zenphoto.org/news/installation-and-upgrading#re-running-and-re-uploading-setup-files

The message tells exactly what you need to do. Download the 1.4.4.5 install package and reupload the setup scripts noted and re-run setup.

You might suggest to your host to upgrade their installation. The current Zenphoto is 1.4.5.1 where uploading the setup scripts is not necessary anymore (that's why the link above speaks of them being protected).

Thanks Acrylian

I've passed this on to the hosting company.

Hi, I am having a similar issue. The message is "Zenphoto has detected a change in your installation. The change detected may not be critical but you should run setup at your earliest convenience." The problem only happens sometimes. It happens when I browse using my laptop inside the network (at home) or outside of the network (at Starbuck's), and even when I use my phone on (WIFI or LTE network). I just browse the photo gallery page without signing in as any user. I only have one album and 10 photos (~300KB each) in it.

Below is my setup:
- Pogoplug E02 (it is not a powerful one, I know :-))
- Arch Linux ARM
- Ngnix 1.4.2
- PHP 5.5.3
- MariaDB 5.5.32
- Zenphoto 1.4.5.1

Any idea?

I think I can answer my own question. I just check the mysqld status and saw this. MySQL server crashed. Do you think Zenphoto is too heavy for a server running on Pogoplug E02?

Besides that I don't know what a "Pogoplug E02" is , Zenphoto runs fine on standard shared hosting. Of course it is very well possible to "overload" as server if you have tenthousands of images in thousands of folders in fine data resolutions.

As mentioned in my previous post, I only have 1 album and that album contains 10 photos, each photo has a size of about 300KB. My Pogoplug is a small box running Arch Linux (I installed it). I host my own family website on it at home. Its hardware specs is: 1.2Ghz single core CPU, 256 RAM.

Sure, it was meant to confirm that this cannot be the reason here. No idea what it could be though.

Thanks for your response. Looks like I can't use Zenphoto. I will try other PHP image galleries to see how they perform on my server, especially to see if MySQL crashes.

We really never heard of this especially with so few images. I would rather suggest to check your server configuration regarding the database.

As far as I know MariaDB is a fully compatible fork of MySQL so that should not be the problem. Unless it is different in something since we only test with MySQL.
