Sorry for the delay. Non-distro installations can be challenging. Seems the installed modules are not synced with the freePBX database. You can fix this by running commands:
amportal a s fwconsole chown fwconsole ma refreshsignatures
Run the last command repeatedly until it does not change anything.
They try a reload from the GUI. You might also want to run yum update, and take a quick look at this doc: http://wiki.freepbx.org/display/PPS/FreePBX-Distro-10.13.66
