This is a fresh install, just downloaded a copy of EEv 7.2.2 (latest) and I get this error in the admin when trying to create channels or entries:
Error: Unable to load requested field type file: ft.fluid.field.php. Confirm the field type is located in the system/user/addons directory
I've double checked the downloaded system/user/addons folder and there is nothing in this directory. I tried to copy the ft.fluid.field.php from system/ee/ExpressionEngine/Addons/fluid_field to system/user/addons, but the error persists.
