File cashing issues in D7 alpha?

It seems that every thing went fine with the inital installation of D7 alpha. The admin section seemed to work fine. But when I went to the index.php home page I recieved this error message: Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 184320 bytes) in /homepages/23/d129869812/htdocs/D7R1/modules/boonex/ads/classes/BxAdsModule.php on line 1437 It would seem to be the cache size that is in error: Is ther asimple fix for this? Or will it require additional programing on your end.
