Your app is causing my website to go blank

I had to remove the app from my website because it was causing my websites to go blank. At this point my website is causing me an error that I have decided to simply delete the whole site and reinstall the site from an old backup file.

In fact, one of your support staff experienced the same issue and could not fix the problem. Although, the staff suggested that I update the wp theme and that it will likely resolve the issue. I will check to see if that will be of any help.
