Unable to edit any page

See below for troubleshooting by Yoast Support. Basically, with specific plugins activated, I am unable to edit webpages. The pages just open to a blank uneditable screen. I updated to the lasted Enfold version (both live and staging). All plugins were updated (including spending $300 apparently for no reason as the issue remains).

Hi Justin,

Thank you for your patience while we investigated this issue. We’re sorry you’ve had to deal with this issue. After reviewing your past conversations, we see editing the checkout page causes a semi-blank screen. We know how disappointing it is when something doesn’t work. Let’s look into what might be causing this on your site.

Semi-blank or white screens most commonly occur when one or more plugins or theme features conflict with another part of your site. Using the Health Check plugin, we temporarily disabled all plugins and switched to a default theme. After enabling WooCommerce, Yoast SEO and Yoast SEO Premium in troubleshooting mode, we were able to edit the checkouts page (image below). After testing various combinations of plugins and theme, we found that the minimum environment required to reproduce the issue is the Enfold theme, WooCommerce, Yoast SEO, WooCommerce Bookings and Envira Gallery Lite plugins (image below).

Using this minimum environment, the issue goes away if we switch to a default theme or deactivate any one of the plugins. Let’s break this down a little more.
• Fails: Enfold theme, WooCommerce, Yoast SEO, WooCommerce Bookings and Envira Gallery Lite
• Works: Failed environment except replace Enfold with Twenty Twenty theme
• Works: Failed environment except deactivate WooCommerce
• Works: Failed environment except deactivate Yoast SEO
• Works: Failed environment except deactivate WooCommerce Bookings
• Works: Failed environment except deactivate Envira Gallery Lite
This tells us that something changes when the above plugins are active with the Enfold theme. We checked the Enfold changelog and see that you are not using the current version of the theme. Enfold 4.5.7 was released on May 10, 2019 and there have been multiple updates to their theme between then and now. The next step would be to update the Enfold theme to the current 4.8.1 version and see if the issue remains when everything is up to date. We’d recommend running the update on your staging site before making any changes on the production site. If you have questions or concerns about updating Enfold, please contact their support team here.

Please let us know if the issue remains after updating the Enfold theme.”
