Ho trovato questa spiegazione nelle faq:

PHP allows each process (ie web page) to consume a certain amount of memory (often this is 8M by default). Moodle sometimes needs to load a lot of files (eg language files, library files) to create one web page, and recent development versions of Moodle running many plugins have started to break the 8M limit for some pages.

As a result you might see errors like this:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 184320 bytes) in /var/www/html/moodle/mod/workshop/lib.php on line 2354

We are taking steps to reduce some of the recent increases in memory requirements before the release of Moodle 1.2, but in the meantime, the easiest workaround to keep full functionality is to increase the allowed memory limit.

1. If you have access to your main php.ini file, then find the line that looks like this:
   
   memory_limit = 8M;
   and change it to:
   
   memory_limit = 16M;
   
   then restart Apache.
   
   
2. Otherwise, you may be able to change this value just for your site by creating or editing a .htaccess file in your main Moodle directory to contain this line:
   
   php_value memory_limit "16M"

Another option is to completely delete modules that you aren't using - you can do this by going to Admin -> Configuration -> Modules.

Ma non trovo alcun php.ini sul server nè tanto meno mi accetta .htaccess.

AIUTO!!!!!
