Not sure if its just me as I haven't seen an issue raised, but I cannot seem to get the addon to load since 10.2.6; WoW says its "out of date" and any attempt to reload seems to be stuck in a 'reload required' loop:

Make sure you have Load out of Date addons checked...

Thanks @ynazar1 !

I noticed the box was ticked, but when I clicked it to 'uncheck' it, nothing happened, then clicked it again and it unchecked, then I checked it off again to turn it on and its now loading!
For whatever reason, I think the GUI was showing a checkbox when it was not actually checked!

You can use wowup to get the latest version whenever i get un-lazy to update the toc. I'll usually fix issues if the addon doesn't work but TOC bumps are low priority ;) .
