The site I posted about here - http://mysitemyway.com/support/topic/wordpress-47-seems-ok - running inFocus 3.9 & WP 4.7 had its PHP version upgraded by the hosting company yesterday from 5.6 to 7.0 (on their recommendation I should add). I never checked what happened (my bad...) but the client contacted me today to say "site broken"...
I got the hosters to revert back to 5.6 and the site is now working again. PHP 5.6 has a current EOL of Dec 31 2018 so that gives me 2 years to figure out what to do, providing of course WordPress doesn't break the site with an update in the meantime. :-(
@OnePressTech - I know you cannot touch inFocus as part of BackStop but have you tested your BS themes on PHP 7.0, and did you find any problems and fix them?
If there's an MSMY code module you had to fix for PHP 7.0 can you direct me to it and the changes required? With luck, said MSMY code module(s) might be common to inFocus so I can try to apply the same fixes (which I can do as I am the theme purchaser). Might not work / be applicable but worth a shot.
