Getting blank page on a Joomla site

Question

The Joomla 2.5+ version site was working for over year but suddenly it is showing blank page.

Also I am unable to save anything in admin panel. Recently I have also made its beta website with new installation Joomla with different db in beta folder under root directory. I don't really think it has created the problem for the original website.

In the error log under admin panel I found this:

PHP Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in /public_html/plugins/authentication/gmail/gmail.php on line 55

In the error log under home directory I found this:

PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 78 bytes) in /public_html/libraries/gantry/core/utilities/gantrylesscompiler.class.php on line 1594

Answer 1

This is a very old question but it is still relevant and so I will answer it. Gantry templates typically need a lot of memory (they really are complex), which means that 32 MB of memory allocated to the page is not enough. You will need more. Try creating a php.ini file or a .user.ini file under the root directory of your Joomla website with the following code:

memory_limit = 64M;

The above will double the allocated memory per page to 64M, if it doesn't work for you then change it to 128M. Typically, for a low traffic website, you will be on the safe side for up to 256M (unless your website is hit with DoS attack).
