Blank buttons on IE?

Can you tell me which version of IE you’re referencing? The icons are using an icon font, which has limited support in IE 8, but should otherwise be compatible across all more recent versions of IE.

I’ve just tested and verified that they work in IE 11.

They don’t work on my site, MLA Commons (commons.mla.org), on any version of IE. I just tested it on IE 11 and IE 10, and the toolbar is there, but the icons are gone. The icons show up on all other browsers.

Hmm. Just checked your site in IE 11, and I can see the icons just fine.

That’s odd. Is it possible that you have an IE security policy in place that is blocking custom fonts?

Hm, that’s odd. I’ll see if I can test it on some more Windows machines, since the only ones I’ve tried it with so far are the MS-provided IE test VMs, but as far as I know, they use default security settings, since they’re just vanilla boxes. Both IEs seem to be loading custom fonts fine, since it loads the site font and WP’s Dashicons font.

Could it be an operating system thing? Both the IE 10 and 11 test VMs I used run Windows 7.

I’m running Windows 7, so no, probably not. Could be a VM thing, I suppose, although that would seem odd.

Browser cache issue seems unlikely on a vanilla VM.

Can you inspect the character and see whether the font styles are being applied?

It looks like the font styles aren’t being applied–they’re there, but crossed out, so something else must be overriding them. Yet unchecking other font styles, like the site-wide font we’re using from TypeKit, doesn’t seem to have any effect–the a11y font styles are still crossed out.

Anyway, I tried loading my site on IE on a Windows computer, and everything seems to be OK, so I’ll mark this topic as resolved. It must be a VM-specific thing going on, although I can’t imagine what it might be.

Bizarre. Well, I guess we’ll assume it’s VM-specific…but how weird. Probably not a major concern, practically, though. Thanks for following up!
