Strange, I bought this add-on, uploaded all the files, imported the add-on xml, and i see the options in my node list when viewing a forum, but nothing works, if i select font awesome, no previews, all just f00c hex, no matter what i select, nothing changes, no icon in admincp, and nothing changes in my forum listing, just default xenforo.
UPDATE: -- I found a setting in my Nerva IPBForo skin to disable usage of Font Awesome on Node Icons.
And now its a bit better, I can select 'icons from server' and they appear in my listing, but still if I pick a font awesome one I have no icon what it is as the preview does not work in the admincp listing, and also when it comes to sub-forums i get not both the font awesome and the custom icon one i picked, but at least its basically working.
Another thing I noticed is for forums the formatting is ok 36 and 14 for px for the custom icons, but for catergories it gets cut off, as you can see here:
So far I got everything working except for the preview of what 'font awesome' icon I am picking in the admincp for the forum node, everything is the same little hex F01c logo, i have to keep trying different ones, until I get the one I want, not sure why in admincp the preview is not working.
