Problem adding new products

Hello I installed the open cart on my website and added all my products into my database, everything was working fine. But then now for some reason, I can't add or edit any products. It just shows a blank page. I already add and removed the SEO Url's and still having the same problem. But everything else works perfectly. I can add and edit new categories, manufactures, etc. Does any one have any idea?

Thanks

Did you edit the code at all? or add a new addon?

No just as is. I used Friendly Url's and then I removed them, and renamed the .htaddress back to htaddress.txt and this keeps happening. Any ideas?

Sounds like a php error is perhaps killing the page. Since you didn't change any files, try reuploading the whole admin folder, and overwrite the current files. Be sure you have your FTP set to "binary"
