I have always kept my addons updated and was able to play fine til I signed on this evening and non are working. The add on window said they were all out of date, checked and I have the newest versions, and even when I click run out of date addons when I log into game they are missing or broken altogether. I ran a repair on the game and it did do a small one to no avail. Not sure how to fix this.
Have you switched over to the new site that’s hosting curseforge Addons?
I believer Twitch is dropping support for WoW Addons this week.
Sounds like your addon manager accidentally installed the Classic version of your addons. Completely exit and restart the addon manager.
