The answer I got from Paul Lesniewski was: SquirrelMail has not yet been updated to work with PHP 7 and this was on May, 2nd, I don't know if this status has changed, but I'm in the same situation check: http://readlist.com/lists/lists.sourceforge.net/squirrelmail-users/2/12332.html So if you find further solutions please share... thanks Moved my working SquirrelMail 1.4.22 installation/config to the new Ubuntu 16.04 LTR platform. Now occasionally INBOX message lines are missing [From and/or Subject will be blank, the line with Date istill shows] and I see these messages in my Apache 2.4 error_log: [Sat Jul 09 22:11:22.905334 2016] [:error] [pid 18805] [client 50.46.232.213:41874] PHP Warning: *preg_replace()*: The */e modifier* is no longer supported, use *preg_replace_callback* instead in /home/www/public/squirrelmail/functions/*mime.php on line 705*, referer: https://mydomain.com/squirrelmail/src/webmail.php [Sat Jul 09 22:11:22.930801 2016] [:error] [pid 18805] [client 50.46.232.213:41874] PHP Warning: *preg_replace()*: The */e modifier* is no longer supported, use *preg_replace_callback* instead in /home/www/public/squirrelmail/functions/decode/*utf_8.php on line 77*, referer: https://mydomain.com/squirrelmail/src/webmail.php [Sat Jul 09 22:11:22.930816 2016] [:error] [pid 18805] [client 50.46.232.213:41874] PHP Warning: *preg_replace()*: The */e modifier* is no longer supported, use *preg_replace_callback* instead in /home/www/public/squirrelmail/functions/decode/*utf_8.php on line 82*, referer: https://mydomain.com/squirrelmail/src/webmail.php [Sat Jul 09 22:11:22.930827 2016] [:error] [pid 18805] [client 50.46.232.213:41874] PHP Warning: *preg_replace()*: The */e modifier* is no longer supported, use *preg_replace_callback* instead in /home/www/public/squirrelmail/functions/decode/*utf_8.php on line 87*, referer: https://mydomain.com/squirrelmail/src/webmail.php Good news is it looks like only 4 lines in two files containing preg_replace() need to be modified for PHP7 to use a preg_replace_callback(). I can edit the files myself if I know what to type. Anybody solved this yet? What is the exact format of the new preg_replace_callback() function for these four source code lines? I spent over an hour searching the web and SquirrelMail mailing list archives and didn't find anything I can use to solve this issue. Now I'm asking for help! BTW, my users like SquirrelMail and are patiently waiting for me to find an answer. * Installation Versions*: - *SquirrelMail 1.4.22 *Plugin's:* * + administrator + calendar + fortune + gpg + html_mail + spamcop + squirrelspell /Checking PHP configuration/...
