main menu not display in browser

Hi

i upgraded my SAP B1 9.1 PL08 to SAP B1 9.2 PL03

now i install SAP B1 Client and SAP GateKeeper on server

i can open SAP B1 on Client (windows)

but when i tried to start on browser, it asked for login but after login it open but did not display main menu

I tried restart services and reinstall gatekeeper

also tried change display resolutions.

does anyone have some suggestions ?
