Hello Everyone, This is my First post on Magento forum 
In my command i get the following 'complication from source' after running the command ''php bin/magento setup:static-content:deploy'' I am in the process of installing an extension but this does not allow me to proceed.
The full message is as following:
frontend/Magento/blank/en_US/TemplateMonster_Megamenu/fonts/font-awesome- 4.5.0/l ess/animated.less variable @fa-css-prefix is undefined in file /home/correoer/public_html/var/view_preprocessed/css/frontend/Magento/blank/en_US/TemplateMonster_Megamenu/fonts/font-awesome-4.5.0/less/animated.less in animated.less on line 4, column 2
2| // --------------------------
3|
4| .@{fa-css-prefix}-spin {
5| -webkit-animation: fa-spin 2s infinite linear;
6| animation: fa-spin 2s infinite linear;
| }
I have attached a picture with the command prompt and the Animated.less file.
What kind of problem am i dealing with? is there an error in the aminated.less file?
Any advice or help would be appreciated.
Thank you in advance.
