Hi @george_long,
To confirm you’ve been using this version since 2016 and this is a recent issue you’re having? Are you able to provide screenshots?
Although I personally can’t advise on a solution, it might be helpful to take a look at the PHP error log- How do I find my PHP error log? - #2 and provide any information this brings up to other users.
Kind Regards,
Patricia
