Add additional information to help when creating graphs from templates

[alcatron]

Im Running some custom graphs to monitor hard drive temperature on synology NAS device which worked fine in 1.2.17... now when i want to add additional disk temperature graphs in 1.2.19 i am seeing this error..

This happens when clicking on "Create" graphs button. Some bug i suppose in graphs_new.php ?

I'm marking this as confirmed, but the source of the problem is likely user error. Check the renaming of the issue for more clues.

I have updated the error message to help in diagnosis.

Still didnt make any difference, updating the new graphs_new.php file

Note, the existing graphs are working fine, its only when new ones to create, ive checked permissions and nothing has changed

[TheWitness]

Hmm, okay.

Okay, that's quite odd. For the host in question, can you please verify the XML files for each Data Query and make sure that the XML file has valid syntax and is readable. Below is an example where you will find "fields". Every XML file should have it and in your case, there is one Data Query where either the XML file is not correct, or is missing that data. I can add more 'debug' to more closely isolate the specific data query also.
