I wanted to share an update regarding the issue you mentioned. After a thorough investigation, I couldn’t find any console errors related to `ReactDOM.render`. However, it’s worth noting that there may be other console errors that are only visible when _**SCRIPT\_DEBUG**_ is enabled. It’s possible that these errors are being triggered by a browser extension or another plugin. * To troubleshoot this further, I recommend checking for plugin conflicts. You can do this by deactivating all third-party plugins one by one, except for ** Essential Blocks**. Simply go to your **WordPress Dashboard**, navigate to ** wp-admin -> Plugins**, and deactivate the plugins individually. * Additionally, you might consider switching to a different theme, such as Astra, Flexia, or Twenty Twenty Three, and then checking if the issue persists. * Please let me know if you have any further questions or if there’s anything else I can assist you with.
