You are wrong Magnus baby. The cache removal feature in the admin panel may remove some of the files but doesn't touch the more important "cache" directory. All it does is empty the "public_cache" folder. I am on Dawg's side here. If the removal link only removes part of the cache, then it really serves no purpose.

How hard can it be to change the script to empty both folders?

There has been more than enough time to get a release candidate out on this project and shipping see more another beta is just a slap in the face to everyone that has devoted hundreds, if not, thousands of hours developing their sites.

Judging by the speed that this project is moving at, one could venture to say that the entire Boonex team is fictitious and there is really only one person working on the creation of Dolphin.
Below is the legacy version of the Boonex site, maintained for Dolphin.Pro 7.x support.
The new Dolphin solution is powered by UNA Community Management System.
