Can't login to admin -- screen just refreshes

[customk1]

per the instructions on another posting...
dumped browser cache etc. and login works. seems issue is related to the recent firefox update. hope this helps anyone else with a similar issue.

I'm running into the same problem. which cache did you clear -- browser cache or the zen cart cache?

thanks,
Don

Just to circle back on this it was a PHP version issue, so the root cause was PHP sessions as DrByte mentioned. There was an apache issue which forced my server folks to recompile apache, which upgraded PHP automatically as well. We reverted to version 5.2.9 and all is ok now.

Hopefully that helps someone else.
