When I insert a new block of type "categories menu block" the main page is blank!!!!

If I delete this block all go right..
In addition, when I access to the "smartsection" thought the main menu I get the follow message:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 92160 bytes) in /var/www/templates_c/%%5A^5A2^5A255BBF%%db%3Asystem_notification_select.html.php on line 72

Try to increase maximum memory in php.ini. Search for something like this:

I am locking this topic as your memory problem is already being addressed in this thread. We don't cope well with double posts around here.

Starting a new thread on the same problem is not going to help - we need to solve your memory problem before we can go on to smart section. You have noted yourself Quote:

You won't be able to fix smart section until this is corrected. You may well find then that there is no problem with smart section. If there is then let me know and i can reopen the post noting the memory error is fixed.
