I am facing a weird issue, url of the post changes when i add/delete tags. For example
https://kotoba.wiki/t/isothermal/9618 is a word isothermal with topic id 9618, after editing it changes to ’
https://kotoba.wiki/t/topic/9618. The point here is the word ‘isothermal’ is changed to ‘topic’
Any idea what is causing this issue, i want to keep the original url after editing also.
