The local config looks good for me. Can you paste a link to the diff ?
Note that HG simply checks if the username/IP is already present somewhere in the report page.

@Framawiki Hi. Thanks for checking. There's no diff however. I got this when hitting "Report user" and then "Check if the user is reported" in the report form of Huggle. Thanks.

I didn't even look on config page, because I am really busy with other tasks now, but I guess the problem is with regular expression for checks of report page. To debug this, you can probably copy paste the report and config page to test.wikipedia.org and test it there. The regex probably needs to be updated, I suppose you have same regex from english wikipedia which is designed for their report page.

I think you should change aiv-section:2 to aiv-section:0

Right now huggle adds the report to section 2, which is usually someone elses report

oh now I see this is not about adding new reports but checking existing reports

however what I posted is true as well, I think Huggle wouldn't be able to add new reports properly as of now

I implemented new option into 3.4.0 in project config which is a regular expression that can be used to find user on report page, this how you can use it:

# Change it so that it better matches the reported user
report-user-check-pattern: '.*$username.*'

@Petrb I'll add that to the Project:Huggle/config (would that work for config.yaml once we find time to do it?)

I think it should work for both

@Petrb I did https://es.wikipedia.org?diff=108247444 - please check :) Thanks.
