Good day.
The situation is in following.
I installed the PHP Expert Editor 3.1 on my computer and the PhpDebugger on another computer in my local network. I'd like to use an external WebServer and to debug my php applications from the PHP Expert Editor running on my computer by means of PhpDebugger installed on the remote computer. I have specified the path to php.exe file: \\Psrv\PHP\php.exe (the remote host named as "Psrv"). So when press F8 I get the following error:

DBG
Failed to run DBG session
reason:
connection to the client address 127.0.0.1:7869 is not allowed
debugger request found in "$_COOKIE[]".
Not sure what it means? Visit http://www.nusphere.com/dbg/ for troubleshooting.

Would you, please, help with this issue?
Thank You in advance.

You shouldn't use neither dbg 2.14 nor dbg 2.16 nor any other commercial version of DBG with 3rd party IDEs. It's freeware version 2.11.23 (the most recent) which is allowed.
