I've also had "Changes made in the editor will be lost" errors when clicking Post Quick Reply button. It looks like the software is trying to submit the message twice for each single click from me- if I refresh the page my message appears in the thread.
Still having problems navigating in Firefox. Some links need a double click to respond. Don't really want to use Chrome......
I am now starting to worry just slightly that Music Radar are not going to choose "Would you like to revert to the last working version of the Forum?"
And today, all of a sudden I started getting the 404s and the having to double click even when I do get through to a page, and the "Changes made will be lost" BS as well. Using Firefox. Clearing the cache seems to have fixed it - hopefully.
