I am developing a module which has a few user controls. In one of them I have two buttons to open other user controls. The logic for both of the buttons are the same just different tables are being used. When I run it locally, everything works perfect but when I upload the module on our website, just one of them works.

Has anyone had this kind of problem before? I had checked the page and module permissions already and since the problem exists even for the "Host", I don't think it is security problem.

I appreciate for any tip or help in advance. 

Thanks Ian, It is solved.

The problem was the install.sqldataprovider on sqlscript folder. I forgot to correct it so whenever I create the module and install it on our website, this was the one which replaces as the stored procedure.
