I'm a long time user of PhpED and just upgraded from V10 to V12. After upgrading the software and the debugger, debugging no longer works on a remote Linux server. Debugging locally using XAMPP works.
I've been using the SSH tunnel option to debug remotely up to V10 with no problems. As an experiment, I unchecked the "Use SSH tunnel" option in debugger settings. After I did that, I can debug a single page using the Internet Explorer toolbar (IE11), however setting the "Debug session" option no longer works. Also, the DBGbar with Firefox no longer works at all.
I'd appreciate any thoughts on what could be wrong.
