out of dynamic memory

Today after trying to use wp-united which is a way to use phpbb3 and wordpress together and it not working I deleted everything to do with the phpbb3 and reverted just to wordpress. I even cleared everything out of my database that had to do with phpbb3. Now I get this error.

out of dynamic memory in yy_create_buffer() in /homepages/24/d198051961/htdocs/hitechvault/wp-admin/edit.php

I have no clue what this means I tried reverting the edit.php file back to the back up but its still here. Any ideas on how to fix this. It is happening when I try to view the list of posts in the admin control panel.
