Hello,
Thanks for contacting us and we regret the inconvenience caused.
It seems like a permissions-related issue, please temporarily disable the firewall plugin or the server-side firewall and see if the settings are saved properly.
If the issue persists, then Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
To determine that, please follow this troubleshooting guide:

Only the site admin would know and your users won’t be affected by this troubleshooting.
Please let us know how that goes.
Perfect, I have spoken with my hosting, and they have solved it. Thank you so much for everything.
Hello,
Glad that helped.
Please feel free to reach out to us again in case you need any other assistance.
We are here to help.
Thank you.
