check your file permissions - follow the readme file in the installation folder of indexU and check and chmod the files again. If you have moved servers manually this could be the problem. are all the settings staying the same regarding database etc?

i checked with permissions they are ok,

also the forumrating admin panel is not working

Im not sure but my first steps would be to rule out cache problems : delete everything in the /cache folder.

line 104 of detail.php is connecting ot the database so if you dont have a cache problem it could be a connection problem. Double check the database details are ok after moving to the new server. are you using linux/cpanel for hosting?

its same cpanel,
one other guy also facing same problem in the server though he is using the lite version of indexu
