Error in the left menu : file_get_contents(http://projeqtor.org/admin/getPlugins

Hi,

I activate the new design and return on the login screen where I log with my credentials.
After that, I was blocked on a blue screen with a beautiful image (a square with a person in a circle with engrenage behind) with flowing circle on it meaned that It try to open projeqtor.

I clean my navigator caches and I recover the log in screen. I validate my credentials and It opens the beautiful new design on the agenda screen.

But unfortunately All the menu on the left part and the project selector on the top doesn't work because of the error  :file_get_contents(projeqtor.org/admin/getPlugins.php): failed to open stream: Connection refused
   in menuNewGuiLeft.php
   at line 353In a red window in the left part of the screen.

Please help me, the new design is so great.

A ProjeQt'Or Fan.
