Udemy courses that worked correctly in whatever version of SeaMonkey I was using 8 (or so) months ago now fail to play. Each lesson of a course begins with a 5-7 second video prelude specific to that course. This runs correctly, but when the actual course content begins the screen goes black, the Status line is "waiting for page-events-ustats.udemy.com".
Debug actions include:
- Clear cache
- Disable AV
- Start SeaMonkey with default profile
- Start SeaMonkey in Safe mode
- Change useragent to Firefox with User Agent Switcher
- Change useragent to Firefox through general.useragent.override.udemy.com in about:config
- Toggled media.autoplay.enabled (I had set it to False)
- Disabled uBlock
When the screen blanks the following appears in the Error Console:
Code: Select all
Timestamp: 2/18/2019 6:36:49 PM
Error: XML Parsing Error: no root element found

Line Number 1, Column 1:

OK, there's an error in the code (maybe?). The videos used to play in SeaMonkey and still do in current Firefox and Chrome: I don't expect to get much sympathy from Udemy support. Anything else I should try or just use FF or Chrome?
