Open Source Document Management System | OpenKM

After upgrading to 6.3.0, Taxonomy (folder tree) didn't show up when using internet explorer.
I've tried IE 8 and IE 11, both have the same problem.
Chrome and Firefox are ok.

OS: Windows server 2003
Database: MySQL

First of all I want to encourage all IT engineers to suggest your users do not use any IE version, it's buggy, slower. Secondly we're sure in IE must going right, I suggest test in a clean computer with IE because probably you got some software installed in this computer like ( antivirus, ad killer or similar ) that's not helping you. What software ? sincerely can be anything.

I am seeing the same results from my machines when trying to view in Internet Explorer. I have tested on a freshly restored computer and I see the same view. I have tested with IE 9, 10 and 11. All show the same way. Firefox shows perfectly. I would love to have all my users move away from IE and to Firefox, but management above me refuses to allow me to switch everyone over.

IE 11 in Windows 8 can display correctly.

OpenKM is based on GWT framework. Google for example advice several year ago that the framework will no longer support IE version 6 because there're was a lot of bugs and were tired patching and doing so specific code for this version, for it they decide do not offer more support for this version. Althought version 7 and 8 seems are better could exists some problems on it. Arrived some moment is impossible maintaining compatibility with historical versions and specially IE family what have a lot of problems. My suggestion is try to give arguments - based on security, stability, performance, etc... - to your users and jump to other browser like chrome or firefox. I you can get a minimal group of users into your company migrated the other will follow there, because they'll see they colleagues have less problems.

Try to reset your IE

Internet Options > Advanced > Reset

then restart IE

Make sure you allow java after IE restarted.
