It seems like I can’t get a break. I was using 2.2, tried to get dropdown menu working on K2 0.95. Worked fine for the frontpage, yet for every subpage the header was broken. Crap. I then tried K2 0.96, then tried WP 2.2.1 with K2 0.96 and dropdown11. No dice. Plus to top it all the subpages went from broken to borked and now to a huge 404 with extra 500 for good measure. Awesome. Time to flatten completely and have a go from scratch.
Edit: All back to normal (hopefully). Strange things had happened to .htaccess. Which doesn’t make any sense whatsoever, I changed nothing about the structure of posts yet somehow that file changed and completely borked the system. Lots of deleting, uploading, head-scratching and hair pulling later and I realise one 700 byte file just wasted a lot of my time.
