Problem edit/add new produts WHMCS

[matheushfl]

Hello, WHMCS Fórums.

 

I have a little problem.

 

Yesterday I was editing a product, the error appeared.

 

Now I can not update the product, or add new products.

 

The WHMCS is original.

 

The page does not load when I add a product or edit.

Look:

Do you know how to solve it?

Thank you.
