@we12a unfortunately this is not a lot of data to go on to figure out what is going on. There shouldn't be any site on a device type - do you possibly have custom fields set on device types or do you have plugins installed that might be effecting this? If you have plugins I'd try temporarily disabling the plugins and see if you can access the page, if you can then it points to the problem with one of the plugins you are using - you could then try disabling them one at a time to see which one might be causing the problem.

If you are using custom fields for device types, can you access a different device type (that doesn't have the custom fields set) and see if it is just this particular one that is having issues?

Thank you very much, after we disabled the plugins, NetBox is now working

Going to close this out as it appears to be a plugin issue.
