Cannot define custom context for virtual extension

Hello all,

i’ve installed freepbx 13 with centos 6.5 on vps
i’ve installed module custom context
i’ve configure 2 custom context
i’ve created some extension
i’ve created virtual extension

Here my problem ;

if i edit extension and go to “other” tab,
i can select from “ALLOWS ALL(default)” to another
click submit and apply change
evering works

if i edit virtual extension and go to “other” tab,
i can select from “ALLOWS ALL(default)” to another
click submit and apply change
here the problem, it return to ALLOW ALL
it cannot take the change

i’ve tried with other virtual extension, same problem
Cannot define custom context for virtual extension

and in meantime,

in user management, if i want to delete a user, i’ve obtain this message ;

Whoops\Exception\ErrorException
Undefined index: uid
File:/var/www/html/admin/modules/contactmanager/Contactmanager.class.php:1391

in module admin ;

Contact Manager 13.0.41.7 Stable Sangoma Technologies Corporation GPLv3+ Newer than online version (13.0.33)

I don’t think custom context is still supported in FreePBX 13. Last time I used it was with FreePBX 2.9 (ages ago). The commercial module “extension settings” does some of the same but works much better.
