I am having a slight issue with InStacks Gallery 3 @Jannis
Instead of having the forward or back chevrons < > for the image navigation I am getting a couple of strange looking icons. Please see screenshots attached.
I just did a test in a new project. Added just the main Foundry stack, a Foundry Column stack with a Gallery 3 - Flex Slider in the left column and headers and text in the right. The slide navigation chevrons looked fine.
I went back to your link and pasted in the original next slider nav content \f002 (since you added the custom CSS) and saw the fl figure you did. I then checked your page and the font for the chevrons (flexslider-icon.woff) is not loading. Your server is returning a 404 error for that file. Without that font file, you’ll see the figure you did instead of the chevron.
@Jannis, are you sure there is a compatibility issue and not just the missing font file?
@scottf, I’d try removing the CSS and republish all files. I think once you have the font file loading from the server, I think things will be fine.
