When running an analyzer in my child-theme, Microthemer generates a PHP debug output, and it messes up the site in tablets and phones, losing custom fonts, losing post styling, mixing images and icons, etc.
I use Divi by Elegantthemes as my building framework.
This is the unexpected PHP debug output:
Notice: Undefined index: draft_mode in /home/ntbwnppd/public_html/wp-content/plugins/microthemer/tvr-microthemer.php on line 7533
Notice: Undefined index: minify_css in /home/ntbwnppd/public_html/wp-content/plugins/microthemer/tvr-microthemer.php on line 7535
We’re heading off to Glastonbury festival in less than 1 hour, so I won’t be available to answer any follow up questions until Tuesday next week. But for now, could you try going to Microthemer’s preferences and saving them (without having to change anything).
That should hopefully be a quick fix for the issue you’re having. I will investigate a better fix when I return next week.
