[Solved]XML error: EntityRef: expecting ';' at line 21

On a fresh install of trixbox 2.3.1,I went to update the FreePbx modules and when I go to check for online updates I get a fatal error:
XML error: EntityRef: expecting ‘;’ at line 21

I tried a manual update of the system from the command line but it fails as well with an XML error. The logs and errors are not specific enough to identify the calling program nor what XML failed.

Assistance is greatly appreciated.

[solved] Through further investigation, discovered customer is using traffic filtering. Arggg.

There was a short (<5 min) were it began working and then stopped. I think this error may be coming from the freePbx upgrade server. My client server is in Washington state. Any Idea?
