This problem may be a plugin or theme conflict. Please attempt to deactivate all plugins and switch to the default Twenty Twenty-Two theme. If the problem goes away, re-activate them one by one to identify the source of the problem.
If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to deactivate all plugins and change the theme for you while you’re still logged in without affecting normal visitors to your site.
It looks you’re using the Elementor page builder. If so, a conflict with that could be causing the issue. I found a thread with what sounds like a similar problem to yours here:
One place to start if you’re willing to look into this more on your own and learn more about your site is to install the Health Check plugin. One of the moderators walks you through those steps here:
It’s not uncommon for there to be conflicts between new releases and plugins, themes, or page builders. A normal step to finding a problem is to disable all plugins and themes and see if that fixes the issues. If it does, then you can start adding plugins or themes back until you find the one that’s causing the error.
However, that’s trickier with a page builder. For a page builder, you’ll likely want to check with Elementor’s support directly to see if they’ve had similar issues and what fixes they’ve found.
Thank you so much for reaching out. I really appreciate that.
I have now got this resolved via Namesco who stepped up once I made a complaint.
It’s been a day of it but I’m back on track now – phew 🙂
