Dashboard admin not displaying

Help me please,
I have success install omeka 2.5.1 on localhost by xampp. All menus and item running well. But after upload on hosting i have problem. I can log in as admin, but the dashboard admin blank only header displayed.
What wrong and what can i do?

Thank for the attention

Can you walk us thorough, step by step, what you did?

You created a local install using xampp. Then you transferred that installation to webhosting? Or you created a second install on the web host?

I transferred that installation to web hosting using cpanel. And i think success connected. But if i log in to admin the dashboard page not displayed properly.

I would compare the files on CPanel and your local install to make sure everything transferred over correctly, including hidden files.
