Blank Error Message Box?


Attempting to make a dashboard so my counterparts and I can more cleanly monitor our environment. However, when I go to Overview > Dashboard > Default and attempt to edit the name, add a widget, or create a new dashboard I just receive a blank error message in the upper right hand corner of the window and nothing happens. If I click the message box, it just disappears. (image attached)

I’m not sure what the error is or even where to find out what it is, any ideas?

Output for validate.php (not sure why it says I have modified files? I have run the command provided several times with no change)

Actually I was able to get a better shot of the web address in the Edge console. It looks like it’s trying to reach out to http://_/ajax_form.php

I’m not sure why the IP or DNS name aren’t appearing in this.

Set base_url to either / or your full web address. lnms config:set base_url /

Will try this first thing tomorrow morning and report back, but sounds promising!

Thank you so much! That was the answer! ran it as the librenms user, all good.
