Two things happen on the members overview page:
- If you click the thumbnail area you go to the member's profile.
- If you click the members name alongside the thumbnail, you go to thei account page. This is essential because this is how I at least, upgrade a membership.
If neither are happening, something has gone wrong on your site. The first question to always ask is: Have I changed any code or have I added a Third party module.
Usually templates only affect the member's side so altering a template shouldn't affect anything.
I'm sorry, but for some reason I missed your original post.
