The export function will not work on my remote server.  Locally, it works.  The files are the same, so I am not sure why the export function only works locally.

One of solution is 

erase and rewrite <?php in controller and in library file on server. It work for me. For development i used WAMP in window but while uploading on linux server file get  converted to Unix format onbehalf it prompt error As 

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by

well.. check if the code generates any error on the server.. set the mode to development and check it..you may get some issues probably..

do some debuging with firebug.. on firefox .. u will surely find some issue out there 

 

Happy GCing :)
