"DOMDocument::loadXML(): Unescaped '<' not allowed in attributes values in Entity, line: 114"

FreePBX 15.0.17.12
Current Asterisk Version: 13.38.1

This morning a client reported none of their phones were connected. These are all Digium D62 and D65 phones configured with EPM. Selecting “use old server” on the phones was successful in brining the phones up and connecting to the PBX.

I did a factory reset on a phone they weren’t using currently and it will not come up. Phone displays “Error handshaking with proxy. Choose a new …”  Phones get initial connection data from DHCP Option 66

I’ve updated endpoint manager to the latest edge version. still no good. All of the extension in EPM are showing as yellow and needing an update. If I go into the template for digium phones and select. “Save, Rebuild Configs and update phones” it crashes.

Arguments

1. "DOMDocument::loadXML(): Unescaped ‘&;lt;’ not allowed in attributes values in Entity, line: 114"

No matter what changes I make to the PBX UI as soon as I submint I get the error above so I don't think it's an EPM issue.  
Module updates were done over the weekend but no changes to the template were made.
I can post more of the data from the error screen if necessary.
