Nextcloud Error after updating/changing mariaDB path

Hello, I am using Unraid and after configuring mariadb, i realized ive been saving it too a cache drive (which i dont have) so, i moved my paths, everything seemed to work OTHER than placing a video through unraid into the folder of my user, it didnt show up. after updating/restarting, i got this error on both MariaDB, and Nextcloud.
