can't update project category content

[shcuro]

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?

can you send your website address, /wp-admin/ username and password and a link to this topic to info@laytheme.com?
