Thanks, I’ve just emailed with the details.

That doesn’t work either. Installed Classic Editor, and the text box is blank and won’t allow anything to be added to it.

Another issue that remains is that I can’t add any images which have been uploaded to the Media Library.

This was from WordPress Support:

We usually see this type of error coming up if a plugin has added a specific type of block; and then that plugin is disabled. In this case the plugin seems to be “tadv” – at a guess that’d be a tagDiv plugin since I do see a few other tagDiv plugins listed for your site.

“Would you know if there were any tagDiv plugins that were removed or deactivated recently on the site?
If not, it might be worth checking with the tagDiv developers regarding this – they may have seen this type of error from their plugin(s) before and can provide more accurate help to restore the ‘Classic Paragraph’ block they provide.

I took the liberty of trying to create a test draft post – in that post it looks like the default WordPress paragraph blocks are working correctly though of course I had a quick look through the full list of available blocks to see if I could spot any tagDiv-specific blocks but didn’t see any there either.”

Are you sure this can’t be from your end? Everything was working fine until Newspaper 12 was installed.
