I wanted to setup xdebug on my server. Most useful will be to set xdebug.remote_host directly from ISPConfig 3. So i opened website settings, and put this: Code: xdebug.remote_enable=1 xdebug.remote_host=18.104.22.168 output_buffering = off in "Custom php.ini settings" But even after server restart those settings are ignored. Instead default are set. Site is configured to run on FastCGI and SuExec. Does anyone had such problem?
