After more comparing I see what happened in my case – but NO IDEA how.
The tables wp_term_relationships and wp_term_taxonomy were dropped from my database. I know I didn’t do it, but I have no idea how it happened. Unfortunately, I hadn’t done another backup since October, so I have to go back to my previous few months worth of posts and re-categorize them – ugh.
Any update on this?
I am experiencing the exact same thing all of the sudden out of nowhere. I upgraded from 2.7 to 2.7.1, but this didn’t happen until a little bit after that – at least a day or two after.
In my admin dashboard it says I have no categories and no tags – but the terms table still has all my categories and tags in it. I tried repairing the database tables, but that made no difference. All my posts show as uncategorized.
As usual, two minutes later I find something that will probably work!
