Hello @cristianovrrj
Welcome to the Bacularis User Group.
To find why this message appears in your environment, I think we will need a bit more details. This is a message about not available page, however we don't know what the page address is.
Could you tell us what exactly you click and where? I mean the scenario that we could try to reproduce it.
In the web server access log should be available an entry with HTTP 404 error corresponding this described situation. Could you check it and tell us what is the address?
How did you install Bacularis? Did you install by binary packages, composer, docker or manual isntallation?
Thanks in advance for providing all details.
Best regards,
Marcin Haba (gani)
