I'm upgrading my WordPress installation this weekend, going from way-out-of-date v2.5 all the way up to v3.0.5.
So far so good - a few glitches, but nothing major.
I know commenting is a little different, but if you notice anything out of the ordinary, please let me know.
I'll post the bigger problems I'm having here, and then solutions as I find them (but I am also open to suggestions if someone else has encountered these):
- WordPress won't accept my FTP credentials - this is annoying, and it is preventing me from updating any of my plugins
- Save Draft button isn't working - these are a few interrelated issues here: it seems like something is wrong with the permalinks, which is preventing me from previewing draft posts. Draft posts are also not saving to the list of draft posts, which means I can't save anything in advance
It looks like this is finally resolved. The root cause was two-fold, I think
- I hadn't been keeping up with regular upgrades (it had been years)
- The underlying database was corrupt, and wasn't allowing me access to everything I needed access to
Even before I upgraded, the access problem existed - it only became noticeable after such a huge upgrade jump, because WordPress had changed how it accessed the database, and now the parts I couldn't access were more critical than before.
The ultimate fix was to scrap the old install completely and start over with a fresh install - new WordPress, new database, everything. I exported all my posts and other content, got my theme set, and then my host essentially redirected my domain to point to the new directory.
A pain in the butt, basically, that could have been avoided long ago if I had been upgrading properly.
Thanks to Otto from WordPress for all his troubleshooting help, and to Chris of thevale.net for fixing everything I couldn't.
