Should be fixed.
In order I've done the folllowing
- Fixed your sources.list file
- Purged all PHP related packages which were from testing...
- Fixed the libxml dependency problem (purge and reinstall to get the expected version)
- Run i-MSCP installer (I've switched to php5-fpm again since this was fcgid due to your previous mistakes)
- ... Small other things which I can remember...
You must now
- Reinstall ioncube loader (properly) if needed
- Check that all is working
Note: I'm not able to access the panel via http://cpanel.prismaticweb.com:50443 but I can access it via http://23.92.76.230:50443/. I don't know if this is expected. If it is not, you must check your DNS.
Last words PLEASE, NEXT TIME, ASK US BEFORE DOING ANYTHING THAT CAN BREAK YOUR SYSTEM
