I'm trying to set multiple include_paths in php.ini file. I cannot get my second include_path to work. I have this setting now, ;include_path = ".:/php/includes:/var/www/vhosts/includes" Code (markup): My LAMP (PHP 5) server uses Plesk to manage domains. It has 3 .ini files, *php.ini, php.ini.saved_by_psa, php.ini.rpmsave*. I have tried to update them all with no results. BTW.. What is each of them for? Which is the one that gets the highest priority?
