Solved 3CX V18 Update "Object reference not set to an instance of an object"

[Fred Vierra]

Recently did the 3CX V18 update. Originally installed with 3CX ISO. Was going to adjust some user settings but when I click on the extension I get "Object reference not set to an instance of an object." error. Tried to delete the extension and make it fresh but when I try to click Add under phone provisioning I get the same error. Any help would be much appreciated.

Try another browser and/or clearing your cache. May be related to the UI changes from the upgrade.

Cleared cache and tried again. Same error. I made the new extension and hit save. Can get back to the extension but when I click add phone same "Object reference not set to an instance of an object." error.

same issues. when updating to v18. i have to login to ssh then do a sudo apt-get update
then sudo apt-get upgrade
then do the sudo apt-get install 3cxpbx

This fixed it for me..

Do you happen to be using a custom templates for IP Phones?

Also, just to clarify, are you saying that you originally installed 3CX v16 using the 3CX ISO and just upgraded to v18 without redeploying? If yes, had you first upgraded to a 3CX v18 Alpha/Beta version or did you go from 3CX v16 straight to the v18 stable release?

I am using a custom template for my Yealink T46's. I can't remember exactly what I modified (been a few years) but I believe it was for different background/screen saver.

Yea, I originally installed 3CX V16 using the 3CX ISO and upgraded from the GUI to V18. Didn't try the alpha/beta versions.

I was messing around last night and did a fresh install of V18 and tried to restore data from an earlier backup ( V16 ) and got the same problem.

Could you give what is mentioned here a shot?

I will give it a shot tonight and report back with the details. I rolled the install back to V16 for the time being.

Understood, do let us know how it goes!

The solution provided in the other forum post solved our issue as well. We had many old templates from years and years ago. They have been removed and all is well in the world.
