Hey @tjhickey - Local has a “parent” php.ini file that we use to generate each site’s unique php.ini at runtime. I get why that is confusing - and what you see is expected, changes made to the parent inside AppData/ will be overwritten.
Instead, you can make changes to the site-specific config - can you check this out and see if it resolves your issue? Modifying php.ini file gets reverted after site restart - #8 by ARed
