PHP version
Doing some testing with 1and1.ca and found that their PHP version is 7.0. Can apparently support back to 5.6 but 5.5 and earlier costs $7 per month per domain.
My sites will not work with 7. What version will they work up to?
I see you now have a MSQLi extension which I assume will address my connection strings but I see errors with UE as well.
