What version of freePBX & Asterisk? Did you update your system before you enabled DPMA?

Here someone describes a similar error.

Unable to enable DPMA in Endpoint Manager Global Settings

Hi, I am attempting to enable DPMA in the Global Settings of the Endpoint Manager. Each time I try, I got the following error message: {"error":{"type":"Whoops\\Exception\\ErrorException","message":"Undefined offset: 1","file":"\/var\/www\/html\/admin\/modules\/endpoint\/DpmaModel.class.php","line":741}} [dpma] FreePBX modules and packages are up to date. What’s wrong? Thanks.
