After installing the Easy Post course format into Moodle 2.1.3+, then purging all caches, it appears that many of moodles themes break in Internet explorer. See images below.
They show the incorrect rendering after purging all caches, then clicking the continue button.
This behaviour is evident in the Kryslte2, Afterburner and Standard themes, and I suspect many more.
To rectify the problem I logged out, deleted the easypost folder from the .../course/format/ folder then restarted my moodle server and things returned to normal.
Krystle2 Theme after purging all caches
Afterburner Theme after purging all caches
Standard Theme after purging all caches
Could someone please shed some light on this issue.
Thanks in advance
