Internal Server Error when trying to access 'Advance Parameters->Configuration Information'

[lepusa]

We are currently running PS v1.6.1.5, and everything is fine except for one issue. I was told by another member of our team that when accessing 'Advanced Parameters>Configuration Information' she was getting this message:

 

CHECK YOUR CONFIGURATION

Required parameters Please fix the following error(s)
Some PrestaShop files are missing from your server.
(/cache/smarty/compile/index.php)
Optional parameters OK

 

I tried accessing 'Advanced Parameters>Configuration Information' myself and got a 500 Internal Server Error after a long wait.

 

I then replaced the missing file '/cache/smarty/compile/index.php' with a fresh copy from the latest 1.6.1.5 release, but the issue remained.

 

Per this post I then replaced the following four files:

 

"ConfigurationTest.php" in folder "classes/";
"AdminInformationController.php" in folder "controllers/admin/";
"smarty_internal_cacheresource_file.php" in folder "tools/smarty/sysplugins/";
"smarty_internal_utility.php" in folder "tools/smarty/sysplugins/"

 

However the issue still remains. The remainder of the site (front end and back end) work fine.

 

What should we do from here?

Seems your server is having a problem with compress and caching. Disable all the settings you made in CCC. In this case you cannot use any compress and cache features.

Thanks for the suggestion. Everything under CCC is set to "No".

 

As for other cache settings, here are some screen shots:

 

 

 

Any further suggestions?

Disable SQL caching (your first screen). SQL caching is not standard setting and if not configured to your database Server,it drives to errors. Standard is file system.

Thanks, we can now access Configuration Information. However we do get this:

 

Check your configuration

Required parameters Please fix the following error(s)

• Set write permissions for the "cache" folder.

Optional parameters OK

 

However the cache folder permissions are already 755... shouldn't this work?

Disable also in second screen caching (not the same as caching in first screen, which is database caching). Seems that your server has no, or wrong configured caching options.

That did the trick, thanks!
