I have just upgraded to joomla 3.2.1 and also installed CB Subs.

Immediately after these upgrades I stopped being able to see K2 articles. I now get Invalid Token whenever I try to view an article.

I uninstalled v2.6.7 and tried reinstalling it. This did not fix the problem.

I then uninstalled K2 again and installed v2.6.8 Dev version. This also did not fix the problem.

Does anyone have any ideas? How would I debug or fix this problem?

Thanks for any help you can give.

I rolled back to a backup of my site and reinstalled the exact same components and now I don't have any issues.

I am still clueless about what caused the problem, but the site is working (less the 5 hours work I lost).

Hello Doug,

Are you sure this is not related to your server setup?
Invalid Token are usually related to that.
