This is why we emailed you on April 27th to let you know you were going to be moved. A lot of people actually read that email and then requested the Python modules they needed before they even moved, and realized they were going to have to change their remote database string, etc. We also posted the same news on this forum, Discord, Facebook, etc. If you had read that email and told us the modules you needed 2 weeks ago there wouldn't have been any 500 errors.
Modules installed.
