New Topic no display / nodebb 0.7.0 Ubuntu 14.10

Dim

Hi Everyone!
First thanks and congrats for this beautiful, fast and functional way to interact with a community.

Experienced with html css and joomla, i started yesterday my first VPS and experience with linux system.
After couples of tries, i successfully installed a functional version on the VPS with a clean distribution of Ubuntu 14.10 with help of this tutorial . (i do own my own VPS on ovh hosting, not like the tuto.)

Apparently everything seems to work, except when i want to post a new topic. A bit inconvenient should i say. Function is working when i try it on the recent post page. Except on this page, whenever i click on new topic nothing happen.
Any thought?

Thanks in advance and keep it up, it's a great product !
(Apologies in advance, my skills in linux system are near from zero, so I might ask real beginner question... but will try to refer to my friend google as much as possible.)

Please install the latest versions of the theme you are using lavender/vanilla/persona etc.

Thanks for your answer!

May i ask if i need to enter a special command to upgrade it or can i just use the npm install command + the wanted theme to override the current one... ?

Yes just npm install will work ie ;

npm i nodebb-theme-vanilla
npm i nodebb-theme-lavender
