Delete the curcache files in all folders.
Make sure the permissions and the ownership of the files is correct.
After deleting the cache files (curcache and curcnt), the problem is the same: an empty screen is shown.
My syslog contains error messages:
Dec 11 17:10:40 boglarka sqwebmaild: Can't create cache file |.Domain.COM-info/tmp/1071159040.M214547P7504_sqwebmail-db.boglarka|: No such file or directory
So, I create a totaly new account (not copying maildirs at all), and the same thing happened....
Hmm.
I have no idea.
