Here it is:
iwwaportal.co.il/index.php/%D7%90%D7%95%D7%92%D7%93%D7%9F

Try to upgrade the extension to the latest version (v. 1.4.0 is used on your site, but the latest version is 1.10.2) and clean browser's cache.

Yap That was it. Thank you for your quick and kind support.
Any suggestions why my icons are gone now?

Hi,

One last question that I've asked in my previous post. After the update the icons where gone. I've deleted my cache and tried several things but nothing. On my local server it works great but on the live website I'm getting the following errors in the console:
iwwaportal.co.il/media/arismartbook/css/fonts/icon_book.woff?-vqfr7h Failed to load resource: the server responded with a status of 403 (Forbidden)
iwwaportal.co.il/media/arismartbook/css/fonts/icon_book.ttf?-vqfr7h Failed to load resource: the server responded with a status of 403 (Forbidden)

Any suggestions please?

and again, thank you for all your help.

Hello,

It looks like a problem with configuration of .htaccess file or some security rules on hosting. It blocks requests which contains a GET variable which starts from "-" symbol. As possible solution you can edit <joomla_directory>/media/arismartbook/css/icons.css file and replace ?-vqfr7h code with ?vqfr7h code. After this clean browser's cache.
