xampp php error

Very strange issue:
If I use the following url on my local server running xampp, it works fine:

This also works fine:

This also works from a remote computer on the network:

All other sites on the local machine using the localhost address work fine

If I use the following on my local machine I get this error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

I am using google chrome
Internet explorer works fine on all addresses including the localhost address

Any ideas
I have cleared the google cache
I have flushed the local dns
I have restarted xampp

I've had issues with Google Chrome cache before, and it's not always obvious how to clear it!  Some of my colleagues have even said, "I don't trust Chrome because of the cache."  You might try using Firefox.  You might also try private browsing

Thanks for the points.  I've come to trust Firefox Private Windows when I absolutely have to avoid cache!
