I have been using Font Awesome icons for a while now but after a round of bug tracking from an external company they found that the font awesome icons were not displaying in some instances.
Version of font awesome is 4.3.0
Versions not working in from external company: iPad4 (iOS 7.1.2) Safari 8.0.2 on Mac OS 10.10.x Safari 7.1.2 on Mac OS 10.9.x Safari 7.1.4 and 8.0.2 Safari Version 8.0.3 (10600.3.18) on Mac OS X 10.10.2 (14C109) iPad Air 2 with iOS 8.0.3
We have internally tested on: Safari 8.0.2
Problem sequence 1 - Login to website - Icons are visible - Log out, close browser, remove all website data, log back in - no icons / squares present
Problem sequence 2 - Login to website - Icons not visible at all / squares present
Website is on own dedicated server, using lamp. Not happening on FF, Chrome or even IE.
If anyone has had the same issue or knows a solution that works please help. We have looked and tried roughly 10 different things i.e. source ordering, updating css, using website link etc etc
