Hello,
when I log in to the FreePBX website, the “Welcome to FreePBX” dashboard is not displayed on the left site. When I access the website I get the following error message in red at the top:
Sysadmin RPM not up to date, or not a known OS.
File:/var/www/html/admin/modules/synologyabb/Synologyabb.class.php:134
Remove the Synology module and the problem will go away.
fwconsole ma uninstall synologyabb
fwconsole ma delete synologyabb
fwconsole restart
Since you are not using the FreePBX distro, that module won’t work. In addition, the following modules do not work without using the FreePBX distro:
isymphony
Any commercial module
If you want a Debian install with a working firewall and all open-source modules and some other extras, check out the IncrdiblePBX implementation of FreePBX.
