Hi,

I've set the comments to registerd only which gives a message under each artikel: register or log-in...
Now i'm trying to ad a login-link directly under this message. Ive read: getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates

But.... any change i'm making to the item.php doesn't seem to have any effect. even if i take out parts of the code the page is still the same. Also emptyd the cache. is there an other file which i have to edit to make any change work.

What am i missing

If you are using multiple K2 templates this post will help you:

If not, and you double checked your folder structure, then a 3rd party extension is blocking the default way of overriding.
