Heyaz,

I have installed the Community Builder onto my site on the CB login on home page when yea click on the register am getting up

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 98304 bytes) in C:\wamp\www\Joomla_1.0.12-Stable-Full_Package\modules\mod_mainmenu.php on line 276

and tried to figure out why could you please help

Many Thanks x:(

Hi
Most likely PHP is not configured to allow enough memory, this error often occurs when you host has PHP configured to only be allowed a very small amount of memory to execute scripts. Installation of large components can require more memory.
Write to your webhost and ask if they can increase the amount of memory in php.ini.
Let me know how you get on.
Kind regards
Lachlan
PS: I had very similar problems with a site hosted at Godaddy.com - no matter how hard you try you wont get them to change this for you - a good host will. You may need a new host...
