Try re-uploading a fresh copy of the theme.
if I do that will I have to read my header or sidebar codes?
Assuming you’re referring to widgets, no.
Thanks that worked but I did lose my custom header. I’m sure its saved somewhere. But the formatting is correct.

Hmmm – that shouldn’t have happened. The theme should have just picked it up from your database. I can only assume that the theme’s developer made some significant changes in the theme since you last uploaded it.
If you’re trying to locate your custom header image, try looking in your Media Library.
