The MU-Plugins! I think that might be it. I just checked the list on dashboard and there acf-builder.php, but there’s also ACF Pro there and it’s the old version! So it’s being overridden by that. Can I just delete the ACF Pro in the mu-plugins folder in File Manager to get rid of this issue then? What about the acf-builder.php abd acf-builder-1.11.0 folder?
I removed the mu-plugins in my staging sites, I’m not sure why these were reinstated when I migrated over. Strange. Any thoughts on to why that is?
