And when I try to isntall plugins from the available plugins menu you I get an:
Invalid plugin key - `_INVALID_` provided.
If it's the blogs plugin I get an:
Message:SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'ow_blogs_post' already exists
(I deleted the table and then I tried reinstalling and got _Invalid_ key again.
