FOP not working after upgrade from 2.3 to 2.4

hello,

i have just upgraded freepbx from 2.3 to 2.4. since that the FOP is not working, the screen keeps reloading and all buttons keep flashing red/green. the panel has not been configured manually and is in the original installation state. is there any know issue with that ? where can i start looking for the problem ?

regards
Jan
