Why is alt-php used when I've specifically chosen to use ea-php?
One reason for this behavior could be because the ea-php version you've selected matches the system default PHP version. When the PHP version for a domain in MultPHP Manager is the same as the default PHP version, PHP Selector is used. If instead, the PHP version chosen for the domain differs from the default PHP version, then the option within MultiPHP Manager is used.
Ensuring your domain is using a different version than the system default, or selecting the option 'inherit' within the PHP Selector will allow for your selected ea-php version to load.
