Suricata not reloading

[redflag237]

Hi,
I cannot reload Suricata. After clicking apply, it takes a very long while and then leads to the error without details attached.

ET Telemetry Pro is activated, Rules BotCC, DROP and DShield are selected with Active/Drop.
Sucicata Log shows no startup. Backend Log shows parsing Suricata config, nothing else, no error.

I tried to reinstall the suricate package, without success. Can anyone help, please?
