I updated 1.0.5 to 1.0.6. At first, things seemed OK.
Now when I try to edit a page in Firefox, it says "(!) Working..." at top right and never loads. I cannot edit elements either.
But in latest Chrome beta, for example, it works fine thankfully.
I am testing Firefox Nightly 14.0a1 (it's 64-bit) with Firebug 1.10.0a5; they load 99.9% of pages OK and do not break on JS errors.
P.S. The forums search is broke again.
Try to run Firefox without any plugin, and see if it works fine. I had many compatibility problems with Firefox plugins, sometimes even in the front end.
If MODX forums search does not work, try to use google instead.
It is intermittent, so it is probably Firefox Nightly and/or Firebug, not surprisingly. Thanks.
