Well, the plugin should ignore the scripts–I had to do some work about how to run the content through the plugin so that the forms plugin I personally use, for example, wouldn’t break (initially, the feed died a spectacularly bloody death), due to embedding scripts in the content feed. So the script itself should be OK, but depending on how it’s handled, it may not be something I can account for.
I believe I’ve corrected the obvious issue which I saw, although I am not sure that it will fix the premature shutdown. Would you be willing to test it for me, before I push it to the repo? If you can, the updated code is on my GH repo. The only code changes are in /includes/class-sendimagesrss-feed-fixer.php. I’ve already uploaded it to my own site and all is well.
If you can do that and let me know so I can recheck the feed, I would very much appreciate it. Is the “shop the look” a plugin, I am guessing?
