First I want to apologize for this experience with our latest release
I am happy to inform you that we have released version 3.6.1 for Elementor Core which contains a fix for the incompatibility issues reported today.
Please try updating this version and inform me if the change helps.
If this doesn’t resolve the issue please follow this workaround:
Just for the time being, it will be a good idea to deactivate all plugins (except Elementor and Elementor Pro), and then reactivate them one by one to find the culprit.
Once the plugin is found, inform us which plugin is incompatible so we can contact the developers. Keep this plugin deactivated for the time being.
Switch your website’s theme to Elementor’s Hello theme. If this solves the problem, keep your website on this theme for now, until this issue will be solved.
Alternatively, you can roll back your Elementor (Core) version from 3.6 to a previous one, which is still compatible with these plugins, such as 3.5.6. You can download a stable version from this link.
Reach out to your third-party plugin support to notify them of the importance of the issue.
