Hello, I have searched, though have been unable to come up with an answer that I can comprehend. With a recent upgrade to PHP 5.0.2 my previous installation of SM (previous 1.5.1) did not function so I upgraded to the Development Version: 1.5.1 My issue is that with the "filters" plugin installed I get the following error when one of the filters would then be being used: [code] Warning: Cannot modify header information - headers already sent by (output started at /home/mail/functions/page_header.php:54) in /home/mail/functions/page_header.php on line 46 Warning: Cannot modify header information - headers already sent by (output started at /home/mail/functions/page_header.php:54) in /home/mail/functions/page_header.php on line 47 SquirrelMail notice messages Category: IMAP Message: Your IMAP server returned an error. Please contact your system administrator and report this error. REQUEST: SEARCH CHARSET ISO-8859-1 UNSEEN UNDELETED From {4} root RESPONSE: 473 MESSAGE: FETCH (FLAGS (\Deleted)) Terminating SquirrelMail due to a fatal error [/code] I then receive on entering the email the following errors: [code] Category: PHP Message: preg_split() expects parameter 4 to be long, string given FILE: /home/mail/functions/imap_messages.php LINE: 926 Category: PHP Message: Invalid argument supplied for foreach() FILE: /home/mail/functions/mime.php LINE: 52 [/code] Can anyone point me to a solution to this issue, or do you know how to fix it?
