I've just downgraded my NNG from version 2.0.66 to the older 1.9.13 because I wanted to use the Nextgen Powertags Plugin, which is not compatible with NNG Versions above 2.0.
Now for some reason whenever I click a tag, I'm just forwarded to a 404-Error page.
You can see what I mean here: http://www.artilstudio.com/portfolio-illustration/
How can I fix this problem?
Thanks a lot in advance!
