Data saves in the database, but shows error in the browser

[eluser]Unknown[/eluser]
Hi everyone,

I have this form that lets the user input data on the browser and save it to the database. Testing it, when I try to save the data, it gives me this error:

An Error Was Encountered

Unable to load the requested file: viewerrorpage.php

I don't remember having viewerrorpage.php included in my project.

But when I try to look in my database, the input data is there! Could the problem be just on my browser?

Any help will be much appreciated.
