Catur.org is "new" if anyone noticed because I moved my entire website from GoDaddy to Digital Ocean because GoDaddy double charged me and didn't respond to my email to reverse the charge.

It's a painful process moving because of the effort of moving things around. Also things like missing thumbnails above..

I already solved this problem over a year ago writing my own custom script to generate the thumbnails. Sadly because of the move I have lost those codes.

That again may take time.. :(
