The code that generates that sql is part of one of the plugins (specifically "Display Thread Readers (2)" which is attached to the "showthread_complete" hook). When you uninstall it, vb should remove that plugin, clearly it isn't - but that's standard functionality, not plugin code. Becasue it's removing the table, but not that piece of code - you get the error.

Do you have a duplicate of that plugin for some reason, and one somehow detached itself from the product ?

Like I said, without you sending me access details there is nothing else I can say or do as I am just guessing / stabbing in the dark - I cannot see what your plugin system is actually doing wrong.
