problems with my site and memory

hi i keep getting error messages mainly when i have uploaded a video, this is the error message

Fatal error: Out of memory (allocated 17563648) (tried to allocate 122880 bytes) in /home/facepla2/public_html/cache/db_sys_menu_member_7a7da5ee1483e0acb7205e9e9a16bc0f.php on line 315

i have no 3rd parts scripts or plugins , any reason for this error , plus my site has no members so its not busy. thanks.

PHP error, you are trying to do something that needs so much memory, edit your PHP.ini to get more memory.. or optimise your script.Thats what I can think of. Hope it helps

Hi all i did was upload a video then i clicked on the home tab then i get the error .

boonex should run ok , its a fresh install.

17563648 - means that you have memory limit about 16M, this is too low, Dolphin requires 128M.

Also it maybe that you have php.ini in different folders and have different memory settings for different directories (it's depending on you php setup).
