ACL.PHP file

Hi guys

I'm getting errors relating to all functions relating to ACL in easy blog.

i get this when going to the admin section of ACL:
Fatal error: Allowed memory size of 209715200 bytes exhausted (tried to allocate 79 bytes) in /home/allseasstaff/public_html/libraries/joomla/database/driver/mysql.php on line 449

and my homepage shows this:

Fatal error: Allowed memory size of 209715200 bytes exhausted (tried to allocate 262144 bytes) in /home/allseasstaff/public_html/administrator/components/com_easyblog/includes/acl/acl.php on line 79

Please advise

thanks
