Update:

Just did exactly that, deleted and Reinstalled extension, after making a backup. With none of my Settings and just the Default it is back to working again on Investing.com going to check CNN.
One of my All-time Favorite Apps! However, it notoriously has problems with CNN.com's Paywall and even More so with Investing.com like the stock Indexes or Futures Pages. I wrote the designer, and he helped me to get it working, for a Little while, then back to not working, at all. Investing.com just doesn't work at all. I may have corrupted the Settings or something idk. I have a feeling, I need to delete and Reinstall the App completely and it *May* work. Wish I could prevent it from happening, in the First Place, would be Nice. Works flawlessly, on Just about every other Site.
