MIME Type and Missing Letters


We're having some learners experience an issue with fonts, where they can't see some letters and the content on slides looks garbled. See attached image. 

We found this article: Learners See the Wrong Fonts or Missing Letters in HTML5 Courses  and proceeded to verify that we had added the WOFF and WOFF2 MIME types to our server. They are installed.  We also tested the course in SCORM cloud and the debug log was clear. 

We used Articulate Storyline 3 to develop the course. Are there any new MIME types we should be installing? Do you have any additional suggestions for how to address the issue? 

Thank you and have a great afternoon,

Hi Maria!

It sounds like you've already started troubleshooting! Thank you for sharing the steps you've already crossed off.

It doesn't look like the image came through but let's start with getting you in touch with our Support Engineers! I'd like them to investigate the file to see which fonts are displayed incorrectly.
