BackupWordPress extension

Hi,

I have been using the BackupWordpress extension on all my websites for several years now, and it’s working on the websites but I’m getting an error in MainWP Dashboard.

“There has been a critical error on this website. Please check your site admin email inbox for instructions.”

This appears when on any attempts to run backups/view existing backups from MainWP. Unfortunately when I try to upload a screenshot I get a message saying image upload is disabled, but if you have an alternative way I could send screenshots, please let me know.

Thanks
Alison
