Please explain. What sorts of problems?
Thanks for getting back to me.
The main issues I can see are when I try an add a post I get a strange looking screen where I cannot access or create new blocks and all the categories, featured images and tags that are usually located to the right are all the way at the bottom of the screen and stretched all the way across. I have screen shots, but am not sure how to include them here. Perhaps I can email you?
Also, I cannot manage any of the widgets. For instance changing images or adding text.
I hope this helps and I look forward to your reply.
Please try installing https://wordpress.org/plugins/enable-jquery-migrate-helper/ to see if that fixes the issue.

If the plugin helps, please contact the developers of the plugins or themes noted in its admin messages.
Thanks so much. It seems to work. The posts are showing up as normal and I can access and make changes to the widgets.
I did however notice that one has to clear all browsing history before the plugin will take effect.
I will carry on testing and let the developers know.
Thanks once again, really appreciated.
