My FWDL page wasn’t right this morning, and I haven’t changed anything. Checking a few other sites it looks as if the problem occurs with multiple extratemp thermometers, i.e. for those of us using stylesheet02.css and InnerContent-02.js. Has anything been changed?
EDIT: seems OK now, along with another similarly affected site . . . It did look like the attachment!
This server couldn't prove that it's gitcdn.xyz; its security certificate is from *.herokuapp.com. This may be caused by a misconfiguration or an attacker intercepting your connection.
My FreshWDL script would not load this morning either, but I have fixed it by replacing the JS files and .CSS files with local copies of these files from the original download.
