Hello all,
  I am getting following error in drupal while clicking on "Administer" module.

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 11520 bytes) in /opt/lampp/htdocs/drupal-5.9/modules/system/system.install on line 2790

Can anybody tell me about how to solve this error.

Regards,
