I've tried every combo I can think of. When I use custom icons with their own path I only get text links. Here's an example of my paths, they should be fine:
I have the icons named exactly like the plugin's.
I've tried a slash at the end of path, and without.
I've tried putting them in root of "icons" (it's not clear whether the 32, 64, etc, folders have to be there or not)
I'm running out of ideas.
Any help appreciated, thanks!
