Saving a firewall rule does not work

[Sven]

Hi all,

I want to save a firewall rule but it doesn't work at all. No matter of the interface it's not possible to save any rule. Clicking on the save button states that it's clicked but no response. Cancel works.
Does anybody experience the same behavior?
Does anybody know how to track this down?
In the log there is no hint that an error ocurred?

Thanks
Sven

I got it, there is an issue with my Brave browser,I am not sure if the new OPNsense version is the problem or the browser itself.
With Chrome it's working.
In my console of Brave browser I found this:
firewall_rules_edit.php:1 Form submission failed, as the <SELECT> element named '' was implicitly closed by reaching the end of the file. Please add an explicit end tag ('</SELECT>')

I'm also having this issue on 25.1. I can't create or edit any firewall rules.

No luck running on Chrome.

This is likely the same issue: https://forum.opnsense.org/index.php?topic=45652.0
