FreePBX web interface is down right after install?

Issue: I ran into an issue during a new deployment with FreePBX 14 distro. After installing and using the first configuration tool that comes up when you go into FreePBX you get the following:

Whoops \ Exception \ ErrorException (E_ERROR)
Class ‘PicoFeed\Reader\Reader’ not found
Image:

 

Resolution: Login to the FreePBX install using SSH and run fwconsole moduleadmin updateall

You may need to run the command several times to upgrade everything.
