Thread:Project:Support desk/PHP Startup: Unable to load dynamic library/reply (2)

Thanks :) I installed Mediawiki on my own PC, Ubuntu Desktop 64bit 12.04. I increased php memory limit to 1024mb from php.ini but still I see error in apache2 log. Honestly I don't know how increase apach2 memory limit. Maybe this happens because I installed mediawiki on a desktop??!
