None of the standard graphs are showing anymore. For any device. It has been like this for a week or so. I am on the daily updates. No errors in ./validate.php. Screenshot below. It also appears that the font recently increased too at the same time

Hi Jarrod,

Having the same issue, by any chance do you see something like this on your librenms,log file

[2026-08-06T10:57:50][CRITICAL] Exception: Error Failed opening required ‘/opt/librenms/includes/html/graphs//auth.inc.php’ (include_path=‘.:/usr/share/php’) @ /opt/librenms/LibreNMS/Util/Graph.php:186

or if you click on the log do you get a

Just to see if we’re running on the same condition

TIA

Yes I do same message and error. Same error message when clicking on any graph.

Thanks for the error message, it looks like graph type is missing.
Can you give me the url for the graph image? (you can exclude base domain)

As for font size changes, we need specific reports of where there are issues because we recently fixed an issue with font sizing, but some places had adjusted to the bug. It is hard to find all those places. Discord or github issues is a good place to report those.

Here are a few of the links. All graphs have the same issue

/graphs?type=device_temperature&from=-1d&device=14

/graphs?type=sensor_temperature&from=-1d&id=487

/graphs?type=device_processor&from=-6h&legend=no&device=27

/graphs/device=302/type=device_availability/duration=86400/from=1786028400/
/graphs/to=1786114800/type=device_processor/from=1786028400/legend=no/device=302/

All of the graphics are not showing at all .

Weird stuff, I wonder why. Not many reports of this, so it must be a low chance to be affected.

Any chance you could walk back git revisions to see which one caused it?

9

I found an issue when the device doesn’t exist it was supposed to show a graphic with a not found message instead of a broken image link. Maybe that was your issue?

10

This update didn’t fix or affect anything on the graphs on my site.

11

I am happy to do so, but I must apologize my git work is very rusty.

How do I go about walking back the revisions?

I’m on daily and is more or less 1,5 week since this happened. I’ve spinned a new machine since I thought it was an issue with the debian update. The auth error on the logs it’s a flucke to disregard ??
