Hi skaero!
thank you for you answer. I don't use any plugins ...
in main.inc.php: $rcmail_config['plugins'] = array();
it is really strange ....
I have also checked via the Java-error-Console of Firefox the website. But FF doesn't display any error there. Only in IE is a error shown .... i have also updated via SVN all JS scripts - nothing helps ....
best regards
Mark
** UPDATE **:
- I have deleted now EVERYTHING (except for MySQL-DB)
- and uploaded all the files from the ZIP-File
- edited the main.inc.php and db.inc.php
- everything set to standard (no plugins - no special things)
- deleted CACHE of DB and of IE
===> STILL the same problem: 'rcmail' is undefined .....
