Hi, I'm running Apache on my localhost and trying to run the profiler with my debugger. I get:
ERROR Wrong version of debugger module detected on server side. Debugger module version of 3.4 is needed to start debug session.

I just upgraded to PHPeD v5.5 so it should have upgraded the debugger, right? How do I do it manually?

Windows Vista Ultimate
EasyPHP as server (see below from phpinfo)

I get this message:
==========================
DBG 3.2.10

Failed to start DBG session


Reason: protocol error ()

Try:

Find in the programs folder the nusphere\phped\debugger\server\Windows\x86... folder appropriate to your system and in there pick the most up to date dbg-php-5.2.dll and copy that into the extensions folder of your php install. You will most likely have a file in there already called php_dbg.dll-5.2.x which is what is now being replaced with the upgraded version.

Then go to your php.ini file and find where it loads the extension:

extension=php_dbg.dll-5.2.x should be replaced with extension=dbg-php-5.2.dll

Restart your server and try to debug.

I had exactly the same issue, but the above worked for me.

I don't know how you figured that out, but it worked. Thanks a ton!

Yeah fixed it for me too.
I use WAMP and found it worked when I put the new dll (dbg-php-5.2.dll) in the xampp\php\ext directory.
