Thread:Project:Support desk/1146: Table doesn't exist

I updated to 1.19 a couple months ago. When I did, everytime I post I get a return error:

Database returned error "1146: Table 'myDB.mw_smw_object_ids' doesn't exist

My edits work just fine. Of course, I want to get this issue fixed ASAP.

I cannot find this table in the documentation. I don't just want to put the table in there.

What is this table about? Can I just create a mw_smw_object_ids? If so, what should I set it as?
