Product Group Labels when try to create a new quotation or invoice appear as Undefined

Before all, a kindly greeting.

I have few days trying to solve this issue and can’t find a way to do it. When I create and new quotation and add a group find than all labels say “undefined” I attach a picture so show it.

If anyone can help me will be great. Thanks beforehand.

Check that your permissions are correctly set in config.php:
‘default_permissions’ =>
array (
‘dir_mode’ => 1517,
‘file_mode’ => 420,
‘user’ => ‘<your-user/owner>’,
‘group’ => ‘’

(make sure that also user and group are set correctly)

In addition change the permissions manually:
sudo chown -R [owner]:[group] .

sudo chmod -R 755 .

sudo chmod -R 775 cache custom modules themes data upload config_override.php

Then you could try disabling unused language packs (Administrator->Admin->Languages and drag to the right Russian, Spanish and, if it is there, also a blank language which may, with the other languages, be part of the problem)

Hi im having the same problem and i have tried out many way but still getting undefined for my add group. Please advise me a clearer advise on how to fix my error. Im new in crm

The above should fix the issues that you see. it might be worth a repair and rebuild after this which can be found in admin -> repair -> quick repair and rebuild

user’ => ‘<your-user/owner>’,
‘group’ => ‘’

(make sure that also user and group are set correctly)

In addition change the permissions manually:
sudo chown -R [owner]:[group] .

sudo chmod -R 755 .

sudo chmod -R 775 cache custom modules themes data upload config_override.php

above is the part i dont understand where i locate sudo and i have 3-5 user i need to edit
example
user’ => ‘<ricky, mary>’,
‘group’ => ‘’
