Can't enter in portals

Hi,
eventually sorry for my bad english,
my problem is that I found that my PG can not pass the portal in the game, every portal I click on doesn't do anything and is very annoying.
Hope you can help me in this issue

Which portals did you try to enter?

The problem is in fact that every portal doesn't work...

instance portal or mage portal or portals in Dalaran/Shattrath, can you be more specific?

I tried the portal to the blasted lands in Ogrimmar, the portal to Ogrimmar in the Northrend, some random mage portal and they never worked...

Is your mouse right click working?
Try simple relog
Try deleting Cache folder
Try disabling any UI addons

Because everything is working for me, mage portals, blasted lands and shattrath/dalaran portals are all working perfectly.

I don't use any addons right now.
I tried a bunch of stuff and some portals works and other just no, I can still enjoy the game but some travel are a bit difficult :/
