I've installed OTRS on apache and it worked fine. Then I've added virtual host, made a copy of first installation and configured virtual host to work with second OTRS. It generally works ok, but I've problem with refreshing data on new phone ticket.
When I select customer from list, form starts updating data on form but ends with an error
It happens only on "main host". On virtual host there is no problem with that.encountered object 'false', but neither allow_blessed nor convert_blessed settings are enabled at /opt/otrs//Kernel/System/JSON.pm line 115.\n
I guess that something is wrong with apache configuration but I don't have any clue what can it be. Maybe somebody encountered this error or have some experience with configuration of apache for multiple OTRS?
