Module installation issue: a non-numeric value encountered

[DJUnreal]

When trying to install the sccp_manager module into a FreePBX system (freshly built, using the latest Raspbian, php 7.3, pre-packaged asterisk and chan_sccp compiled from source), I get partway through the installation either via the GUI or CLI (have tried both). The most recent attempt, using source pulled from this git repo and the install process at https://github.com/PhantomVl/sccp_manager/wiki throws the following error:

In install.php line 744:

As an aside, it also throws warnings that:

!******! 'amportal' IS DEPRECIATED. PLEASE USE 'fwconsole' !******!
FORWARDING ALL COMMANDS TO 'fwconsole', OUTPUT WILL BE MODIFIED
CONTINUING TO RELY ON AMPORTAL WILL HAVE UNDESIRED CONSEQUENCES

Might want to update the instructions for that.

Thanks - the new version worked nicely for installing via the GUI
