Lay Theme Forum

hi,
on my website joaoervedosa.com i'm trying to update the category 'work' and everytime i click update it send me back to the website without any changes being made.
i've disabled all plugins and it's still happening.
can you help identifying what's causing this and how to solve it?
thanks in advance.

whenever i click 'update' on the project category 'work' that i've created for my website it sends me back to a 'page not found link': https://joaoervedosa.com/wp-admin/edit-tags.php

i have two project categories 'work' and 'play'.
this only happens with 'work' which i can't even delete if i want to.

can you help me with this?
