Well, I did something dumb… I took a backup of a FreePBX 11 system, upgraded to 13 and things weren’t working properly with Dahdi, so I restored the backup from version 11 to the current version 13 system without thinking that through and that has effectively crashed the system.
Now when you load the GUI, you are routed to the “Please Select the default locales of the PBX” page. Clicking submit does nothing, and clicking apply config presents this error:
exit: 1
