Syntax Error due to WordPress 5.5 – WPBakery Page Builder

[bradthebluefish]

Upon updating the millwaymarina.com website to WordPress 5.5, I could no longer edit certain modules (i.e. Text Box, Icon Box) within the WPBakery Page Builder. A syntax error will occur within a wp file (wp-load.php).

All other plugins were up to date. All were disabled to see if that helped with the syntax error. The only things that worked was reverting back to WordPress 5.4.2.

As a developer, my assumption is something is wrong with the wp-load.php file OR the user's database needs to be conditioned better upon upgrading to WordPress 5.5.

NOTES:
1) Because I use the free plugin, I only use the frontend editor within WPBakery Page Builder.
2) No screenshot of the error as I forgot to take one before I reverted back to WordPress 5.4.2

Hi there @bradthebluefish, this sounds like something that might be related to the removal of jQuery migrate in WordPress 5.5. Usually, you can fix this problem by adding this ​plugin. To be clear, this is meant to be a temporary fix, and the real solution should be working with WPBakery Page Builder to get the change fixed in that plugin. It might be worth opening a support issue there.

You might also take this question to the ​support forums where this issue is being tracked. I'm going to close this ticket as it seems to stem from a plugin issue, and not WordPress core specifically.
