Incomptibility between Enfold 3.5.4 and WPML latest version.

I have an incompatibility showing up between Enfold and WPML that is new. The “Theme and Plugins Localization” page is blank, which is where the basic Theme and WP translation setting are making it impossible to translate or manage the translations.

I have gone through everything. No plugins are conflicting. I have disabled them all except Woocommerce and WPML. Then checked the themes and tried with all plugins activated in the “TwentyFifteen” theme. The Theme and Localization page opened no problem. Plugins activated or not make no difference.

In the theme “Enfold” when all plugins deactivated, the page Theme and Localization page did not open. So the incompatibility seems to be within the Enfold theme—probably due to the latest WPML update. I have used WPML in Enfold for over a year and translated another site that is essentially identical to this one with no propblems. However, that same site now has this issue even though it has translations done. So, this incompatibility issue is brand new, but renders WPML multilingual useless.

I must debug this issue or I will have to reimburse the client for many thousands of dollars and the whole ecommerce business becomes a liability since they are in Montreal and by law must have a French website or get fined. This is a big financial liability.

Please help me debug this on the staging site I will give which is a duplicate of the live site.

I am turning the WP error logging off for now, if you want it on again please alert me.
