Hello Peter,
Thanks to share your problem.
The above information you are showing that your plugins have created glitch into the database and this will need to make updated before running your blog.
You must clear your database and remove unnecessary updation from the WP-OPTION data table via p database access.
I face the same problem with my blog [link redacted] and after remove the plugins quires executed by the plugins. The blog working fine.
