Pro Features No Longer Working After Using WPEngine Migration Tool!

Support
#1

I’ve also posted this in the Support Forum but, wanted to get as many eyes on the issue as possible in case a solution exists among peers. :slight_smile: Thanks!

#Main Issue:
We are in the process of migrating to WPEngine and are having issues with using the Pro theme’s main features and editor.

The following Pro features are not working:

  • Headers [/pro/#/headers]
  • Content [/pro/#/content]
  • Footers [/pro/#/footers]
  • Templates [/pro/#/template-manager]
Clicking any of these four sections produces these same 2 JavaScript warnings

##Things We’ve Tried:

  • Completely removed Pro theme and reinstalled
  • Updated everything:
  • Pro Theme from 2.5.5 to 3.0.4
  • WordPress Plugins (including those included with Pro)
  • WordPress Core from 5.2.3 to 5.2.4
  • PHP from 7.2.7 to 7.3
  • Clearing Cache (both server-side and client-side)
  • Confirming CDN is disabled (was never enabled)
  • Reattempted the site migration multiple times (in case there was a hiccup)
  • Reset .htaccess and re-saved permalinks to reset .htaccess file.
  • Checked allocated memory is sufficient (was already at 256M)
  • Asking WPEngine for Support — 3 different times — and it was suggested to contact the theme author.

Similar Issues in the apex forum:

Current Setup vs. WPEngine:

• PHP 7.2.7        • PHP 7.3
• Pro v.2.5.5      • 3.0.4
• WP 5.2.3         • WP 5.2.4

Looks like I’m onto something…

I’ll be updating the other thread rather than this one.
