Delete page

A while ago I changed my username to a new one because I wanted to delete my old name from the internet for certain reasons. All the discussions done before were changed so that my old name would not appear on google. But there is one that still retains the old version despite having already changed it. Can you delete the next page? it is urgent: https://translatewiki.net/w/i.php?title=Thread:User_talk:Navhy/Por_favor,_non_sigas_cambiando_as_traduci%C3%B3ns_sen_consultar&lqt_oldid=81444

I tried deleting it, but I got an error while doing so. Nikerabbit?

Please :(

and if you can not delete at least edit my old name by "Iváns"

Why is it not possible to delete the page, even if it is change the name of my old nickname for the new!!!

Hi, how is this? it's taking too long, if it can't be deleted (which seems weird to me), can't you edit it to remove the old name and replace it with my current one? Nikerabbit?

Deletion is not possible due to https://phabricator.wikimedia.org/T256590.

I tried to rename the thread, does that help?

It seems that the linked page no longer exists, thank you very much!
