Guys, I am very thankful that I now have these sites back up - but it does beg the question why did this error arise in the first place? Any ideas anyone - it seems uncompressing the JS and possibly CSS fixed this issue.... Why would the manager be working fine for 3 months, then suddenly fall over like this? Does the manager call in external jQuery library for instance? Is it calling the latest version and a new version came out which the manager does not support any more? Have other 2.2.5pl sites fallen over like this lately? Is this an isolated instance or is it widespread across 2.2.5pl versions?
Be good to get to the bottom of this!
Found this on the rtfm >
