Error Message: ( ! ) Warning: Illegal string offset 'css' in /Users

I get this error when I try to open the site

Warning: Illegal string offset ‘css’ in /Users/henkan/Local Sites/local-to-live/app/public/wp-content/plugins/elementor/core/page-assets/data-managers/base.php on line 242

( ! ) Fatal error: Uncaught Error: Cannot use string offset as an array in /Users/henkan/Local Sites/local-to-live/app/public/wp-content/plugins/elementor/core/page-assets/data-managers/base.php on line 246

Since to days ago I get this message every time I try to open the site.

Troubleshooting Questions

  • How to solve it?

  • If I store a Backup of the site - would relaunching it help? I worry that if it does not I will lose a lot of unsaved data since the last backup.

Replication

I have not made any major changes - I only remember playing with the core theme font, but now the site is giving me Error 500 if I try to make any new changes.

Hi, go in Elementor-Tool and regenerate CSS and Data + Sync Library.

For me, that work, hope for you too.
