WordPress MU

I've upgraded and run the upgrade utility and its now throwing errors like

WordPress database error Table 'canalblogs.wp_3_post2cat' doesn't exist for query SELECT p2c.category_id AS cat_id, COUNT(p2c.rel_id) AS numposts,'

and

<code>WordPress database error Table 'canalblogs.wp_1_categories' doesn't exist for query SELECT * from wp_1_categories WHERE category_count > 0</code>

And the tables don't exist in the database

Looks like a plugin using depreciated functions/variables.

Yep, that'd be my guess, a plugin looking for the old categories table.

Turn off some plugins and see what happens. Might have to take some out of the mu-plugins folder depending what you have in there.

Its all very odd I've gone through every option and plug in and I can't find it and actually searching for text in the files doens't show anything.

Its been one of those days

Did you take the old site category plugin and stuff out of mu-plugins?

That was a "upgrading to 1.3" kinda step.

Those were all moved into one of the mu files.

As far as I can see and as I say it all seems to have stopped. I'm trying to remember what I was doing round that time. I might have been playing with the cache configuration but....

Yeah, but if there were left behind, he'd have a WSOD.

Not necessarily.

And I feel like a complete idiot as its a chunk of my own code that I thought I'd got rid of. Was searching an archived copy of my code on my Windows Laptop and its decided not to search php files which is why I couldn't find it!
