Hello, sorry it took so long, never used this forum here.
Can you send me the User Agent String of the comment? Just login, go to the comment and copy the text shown when you hover on the *(asterisk) after the comment.
I suspect that this cannot be corrected, since your browser must be sending a generic “Linux” in the user agent, and not “Ubuntu”. I have seen that behavior, but send me the UAS and I’ll see if it can be corrected.
Thanks,
Bruno
