Server Error in /Hap Application

[nyates]

Have installed HAP 8.4, All working for administrator user account but when trying students I get something is wrony after logging in with drives. When clicking My files I get Server Error in /Hap Application page - Index and count must refer to a location within the string. Parameter name count. Not sure what this is or how to resolve. Have attached screenshot.
Thanks
Nathan

Will be fixed in v8.5. Open ~/app_data/hapconfig.xml


Find the filter for Powerpoints, remove the trailing semi-colon ;

Thanks Nick, This has resolved the page appearing -server error in /Hap application. Still testing as a student user I get on the home page Something is wrong in red and also when clicking My files tab. Have attached screenshot. I have looked at all share and ntfs permissions for this user and all seems okay. If I try any member of administrators group user account the mappings work okay. If I add this student testuser as a test to this group this also works okay- Any idea what could be wrong. Thanks
