wordpress categories missing

Question

Please note, this is not a theme or so issue. The categories are not showing in the admin panel, however it denotes that there is 6 categories. They are also visible in the databse.

Recently something happened with the hosting and any php move_upload functions started giving error about missing tmp path, so i created a local php.ini file to point to the right tmp folder home/user/tmp and that solved the issue

this however seems to be linked, i tried setting these in wp-config define('WP_TEMP_DIR', '/tmp'); define('DBCR_CACHE_DIR', '/tmp');

but no avail
