When we activate the caching mechanism of Joomla (Configuration => System -> Cache Settings => Cache => "ON - Progressive Cache") things look like are working normally, until at some point the Greek Pages stop working.

The website (favela.gr) is multilingual in English and Greek. The English pages have no issues at all, the Greek pages seem to produce corrupted cached information. The only way to restore the problem is to manually Clear the cache.

Digging in the problem I came up with the following warnings:

[18-Feb-2015 12:06:17 America/New_York] PHP Strict Standards: Declaration of JCacheControllerView::get() should be compatible with that of JCacheController::get() in /home/favela/www/www/libraries/joomla/cache/controller/view.php on line 137
[18-Feb-2015 12:06:17 America/New_York] PHP Strict Standards: Declaration of JParameter::loadSetupFile() should be compatible with that of JRegistry::loadSetupFile() in /home/favela/www/www/libraries/joomla/html/parameter.php on line 512

Both classes override a function and they change the parameters. Especially the Caching controller not only adds more parameters, but completely changes the functionality of the original two parameters. This can impose a serious issue if the core framework of Joomla calls this function passing the initial set of params.

I am not sure if this is the problem, but I got nothing else so far.

Are there any know issues with the caching mechanism for multilingual sites?

Is there an update that at least fixes the two issues above?

No update or help on how to resolve this issue?

Can anyone help us?

Hi,

I have built multi-language joomla's before but never experienced this kind of problem. I can assure you; this problem can't be related to StyleMart, not a chance. This is a much bigger problem than a "template" can cause.

It is obvious; the problem is something to do with the Joomla Core and if the problem is related to core of joomla; usually there is "no patch". All you can do is to make sure to have the latest Joomla2.5.xx version.

My another idea is; this problem can also be related to your server's PHP version as well, Joomla.5.xx is pretty old by now, so using very new PHP version (PHP5.4 per say) can also cause some problems. Install the same website on your localhost (AkeebaBackup will help you carry your website from production site to localhost) and try changing the PHP version. Most localhost server, i.e:MAMP, lets you change the PHP versions by simple clicks, then check if you experience the same problem on your localhost when you change the PHP version.


Regards.
