Whenever I go to mysite.com or mysite.com/install I get the following error:

Fatal error in exception handler. Check log for Exception #1423544693

When I check the error log it says

 QUERY: SELECT value FROM social_config

The problem with that is I have cPnale, but I could have sworn I did install exif and gd. MBString was also installed but for some odd reason will not work for the life of me.
Also,t he database issue at the bottom. I thought when I go to install that it will automatically put everything in the database that I need it to?
