Domain Mapping Fails after Uninstalling Upfront Builder


In a previous ticket I drew attention to a fatal PHP error caused by having Upfront Builder, Multisite, and Domain Mapping enabled simultaneously. I have since disabled and deleted Upfront Builder and experienced temporary resolution, only to experience a recurrence that causes me to have to disable domain mapping.

The error I am getting is as follows:

[Thu Nov 03 22:43:57.935151 2016] [php7:error] [pid 1350] [client] PHP Fatal error:  Uncaught Error: Call to a member function get() on boolean in /var/www/ trace:n#0 /var/www/ Domainmap_Module_Mapping->redirect_upfront_to_mapped_domain()n#1 /var/www/ Domainmap_Module_Mapping->redirect_front_area('')n#2 /var/www/ do_action('template_redire...')n#3 /var/www/ require_once('/var/www/better...')n#4 /var/www/ require('/var/www/better...')n#5 {main}n  thrown in /var/www/ on line 1117

This line refers to a check for Upfront (aforementioned in the prior ticket). I have since disabled and reenabled Domain Mapping. Multisite works when it is disabled, yet Domain Mapping does not (duh). Upon reenabling, Domain Mapping works again: but only for one of two sites. works as it should, yet both the normal ( and the mapped domain ( simply lead to the multisite default page (

All of these sites were working normally after I deleted Upfront Builder, only recently recurring for unknown reasons.

How can I have my pages map normally?
