Steps to Reproduce:
- Citation > Cite web
- Don't add any information. Just click "Apply changes".
Result: <ref>{{Cite web|url = |title = |date = |accessdate = |website = }}</ref>
That's pointless. If the fields are blank, don't add it (or remove it).
Steps to reproduce, part 2:
- Citation > Cite web
- Don't add any information. Delete all the parameters.
- Click "Apply changes".
Result: <ref>{{Cite web}}</ref>
That's even more pointless. If there are no parameters, don't add it (or remove it).
Reproducible: Didn't try
(The "invalid" parameter in that diff was manually created by me. I don't think you can do anything to help the person adding invalid parameters, because there's no way to differentiate between invalid parameter names and valid names that don't happen to be defined in TemplateData.)
