I am trying to upgrade from ISPConfig 2.0.7 to 2.2.6, and got the following error: Code: ERROR: The PHP binary coming with ISPConfig does not work properly on your system! The installation routine stops here! I tried the install again and got the same error. My mail seems to work using a client, but I can't log onto ISPConfig. I also couldn't find any backup files in the tmp folder with today's date. Please help! Thank you.
