Just to update my efforts before I head to bed:
I installed health check and will post the latest diagnostic below in case it helps at all. I disabled most of the plug ins aside from the reviews one and the health check one. I updated the PHP to the latest version. I have set the Theme to NineteenSeventeen as recommended. I restarted my computer to clear the cookies. I have run out of ideas for one evening.
One thing the health check has mentioned which might be the cause: Scheduled events A scheduled event (site-reviews/schedule/session/purge) has failed to run. Your site still works, but this may indicate that scheduling posts or automated updates may not work as intended.
I wonder if this is the culprit?!
I look forward to hearing from you tomorrow,
Kind regards,
Tim
