Need help to rebuild database (9 posts)

    Ever since I moved my blog to another host (Dreamhost) last summer, I've been having strange little issues that I've posted about before, but found no real answers. Things like always getting a "Saving post . . ." message in the edit screen (the post does get auto-saved, but the message gets stuck), unable to get to some plugin settings screens (insufficient permissions), and -- this is new -- inability to upgrade WP automatically. And a few other things, none of which are, on their own, catastrophic, but together are a pain.

    To try to solve this, I've tried turning off and deleting all plugins, refreshing all the WP files, switching to the default theme, etc. After doing some research, I really think it's the database that's to blame. I thought it had something to do with prefixes, but they all seem to be fine (although I once used a security plugin on the install at the old host that I think did something with prefixes, but like I said, all of them seem to properly have the wp_ prefix).

    So now, I think it's time to just go with a fresh database. Can anyone point me to some step-by-step instructions on how to do this without resorting to a completely fresh install?

    Thanks

    Would emptying the tables of data and then running an import of the XML export file work?

    It should do.

    Ok, so my next question would be, how would I do the import? If I've cleared data out of the DB, I'm assuming I won't be able to access the admin area.

    Export the data first, clear the tables out of the db, re-run wp-admin/install.php and then import the .xml file.

    Awesome, thanks. I'll give it a shot tonight.

    It sort of worked. I deleted all the WP core tables and then ran the reinstall, and imported the XML file. All my settings, widget configurations, etc, were gone. I had mistakenly thought that the file contained settings, which it didn't, so I had to comb through the settings section and try to remember what I had set the options to. But that's not a big deal. Unfortunately, except for solving the failed auto-upgrade issue (which I'm psyched about), I'm still having that weird stuck message in post edit: "Saving draft . . ." Luckily, it's not a big issue, just strange.

    For future reference, is there any way to export settings (in addition to the post data) in case one wants to do a database rebuild?

    Thanks for your help!

    The only way to do that is to import an .sql backup into the new db. The problem there is, if you setting up a new db because of problems with the old one, you may just be copying the issues across to the new db.

    So true. I didn't do it that way because I was worried about. But I also didn't actually delete all the tables, just the core WP ones. I kept some of the third-party plug-in tables in order to keep some of the settings -- which actually didn't work. The fact that my install is _still_ showing problems is making me think the problems lie with those tables. I think I need to delete _all_ the tables and try it again.
