Ok, Here is the complete error message shown in a browser(frame)window when i try to open Squirrelmail in a Portal(iframe): "This content may not be displayed in a frame. To protect the information you entered on this website, the publisher of this content has prohibited to display the content in a frame. Possible approach: Open this content in a new window" I had a look at the file functions/page_header.php and modified the following line header('X-Frame-Options: SAMEORIGIN'); First i comment out //header('X-Frame-Options: SAMEORIGIN'); --- same error message as written above Then i set it to: header('X-Frame-Options: '); --- also the error message appears After that i set: header('X-Frame-Options: _parent'); --- same error Finally i set it to: header('X-Frame-Options: false'); --- same error This values didnt work. Is there something else i have to modify? Or have i to modify something else, like the value for $frame_top in the config/config.php ? Thanks in advance. -----Ursprüngliche Nachricht----- Von: kwadronaut [mailto:kwadronaut@xxxxxxxxxxx] Gesendet: Dienstag, 7.
