add comments in all module stopped working!!

Comments stopped working in all my modules.

i checked it with settings set to public or just members nothing is added.

please help!!

can you add comment using an admin account?

nope!

i tried everything.. as normal user or as admin.

how can i restore the comments table lines in the DB so my comment blocks work again?

is there a reference somewhere...

it got killed after un-installing the gwall(groups timeline) module
