Dolphin.Pro Licenses cannot activiate

Hi all,

I bought a Dolphin.Pro Licenses for my Company Dolphin site (7.2.0).

After install the Dolphin 7.2.0, I try to activate the Licenses by copying the code from http://www.boonex.com/market/licenses

However, In my dolphin Administration --> License.
When i copy the Licenses code and "REGISTER", it always show "CURRENT LICENSE - TRIAL"

In http://www.boonex.com/market/licenses page, it also show the Licenses key "not registered".

I have try several time, but i still cannot register my Licenses.

I would like to ask is it any special protocol / port need for registration, since my Linux server block all non-necessary ports. Is there any special setting in Linux?

Thank you very much.

allow_url_fopen php setting must be On, you can check this and other settings on audit page:

admin panel > tools > host tools > audit

also outgoing connection to license.boonex.com to port 80 should be open

 Thank for you suggestion, it sloved
