Received an Error message after entering and saving a new glossary item

Please someone tell me why this is happening to me! After creating a glossary entry, I needed to save it. Then, when I clicked “Save” I got an error message which has nothing to do with it. This is causing returning to the entry page with three errors.
Server not found
Firefox can’t find the server at view.php
• Check the address for typing errors such as ww.example.com instead of www.example.com
• If you are unable to load any pages, check your computer’s network connection.
• If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Try Again
How do I save an entry without seeing this error on my screen?
