What a complete n00b. I couldn’t get my blog theme to look like it should, so I did the whole reset thing. Deactivated all my plugins. Cleared all caches.. Updated stuff. Exported my entries. Reinstalled WordPress.
So I went all hardcore. Back to the host. Delete WordPress. ( you can see where this is going. ) reinstall WordPress.
Success! Theme works perfectly. Reimport posts. All present and correct!
OH WAIT A MINUTE. All media now gone!
Good thing is I was starting fresh anyway, just a bit annoying that all the pics, zips, source stuff will have gone. I could restore a backup from host, but I don’t think the old stuff is worth worrying about.
So it really is a fresh start!
