I would like to set my own title to the tag view. I have tried couple of things (in .../default/tag.php):
The title just won't change. What might be the correct way to override the title?

Thanks.

Hi Ari,

Tag page titles are created dynamically from each respective K2 tag name. In K2v3 we will be able to assign Extra Fields to a tag (use the extra field with a template override to control all meta data - which currently can be done with items).

Here are two options that you can execute with K2v2.x

Option #1
You could use the NoNumber ReReplacer extension (pro version). Basically, you would create a search for each tag title tag and replace with you desired title.

Option #2
Use a SEF extension like sh404SEF, which allows you to control each page (SEF URL, title tag, social meta tags, etc.)

I hope this helps,

Joe Campbell
