 * I have a number of questions and requests to help you analyze the problem.
 * From which WordPress version did you update?
 * Where did you see the errors?
 * Can you deactivate all plugins and see if the message still appears? If not, 
   re-enable the plugins one by one until the problem occurs again. This plugin 
   can help with the troubleshoot mode: [https://de.wordpress.org/plugins/health-check/](https://de.wordpress.org/plugins/health-check/)
 * Can you also please activate a default wordpress theme? E.g. the TwentyTwentyTwo.
   Does the problem still occur then?

 * Thank you for the reply. Here are the answers:
 * 1. From the last version since we keep all our websites updated.
    2. Errors are
   in WP Admin > Inspect 3. After the deactivation and activation we found the following
   two plugins causing this problem: Elementor Pro Version 3.6.2 & WooCommerce Version
   6.2.0
 * Any ideas on how to fix this?
