I got this message after migrating a Worpress setup to Trellis
You must update the max_input_vars php setting to at least 5000
So I added the variable to my staging environment vault group_vars/staging/vault.yml
I reprovisioned the server
trellis provision --tags php staging
No success I also added for testing to the environment variable to group_vars/all/vault.yml
I am not sure what step am I missing. Still get the exact same error message.
