When editing dashboard, I could add a widget with its default settings, but when I tried to edit the settings I was not able to save the settings. LibreNMS showed an empty error dialog in the upper-right corner.
However I could edit and save it successfully when I disable the Modsecurity module in nginx (set to
modsecurity off in nginx.conf). Just that ModSecurity is a necessary module in that server, so disabling that is not a solution for me.
I couldn’t find any document / discussion about this issue on Internet.
The output of ./validate.php:
$ ./validate.php ==================================== Component | Version --------- | ------- LibreNMS | 22.3.0-3-g9c127bfd4 DB Schema | 2022_02_03_164059_increase_auth_id_length (235) PHP | 7.4.28 Python | 3.9.2 MySQL | 10.5.12-MariaDB-0+deb11u1 RRDTool | 1.7.2 SNMP | 5.9 ==================================== [OK] Composer Version: 2.2.9 [OK] Dependencies up-to-date.

Any help will be appreciated.
