Suggested PHP Settings for Directorist Plugin

Hello.

New installation, and we are having trouble where not all Setting changes are being reflected on the frontend (but they show correctly in the Settings page).

Thinking/hoping it could have something to do with the some PHP settings?

Is there a list of recommended settings for things like these?
– post_max_size
– upload_max_filesize
– max_input_vars
– memory_limit
– max_execution_time
– max_input_time
– session.gc_maxlifetime

Thanks in advance,
Atg
