Here’s a couple of fresh errors to show that the old syntax does not work in the current Apache:
[Tue Aug 02 07:25:41.916801 2022] [core:alert] [pid 3520:tid 692] [client 1.1.1.7:36658] C:/web/site/.htaccess: Invalid command 'order', perhaps misspelled or defined by a module not included in the server configuration, referer: https://www.domain.sfx/wp-admin/plugins.php
[Tue Aug 02 07:26:30.760003 2022] [core:alert] [pid 3520:tid 692] [client 1.1.1.7:36686] C:/web/site/.htaccess: Invalid command 'Allow', perhaps misspelled or defined by a module not included in the server configuration, referer: https://www.domain.sfx/wp-admin/
This is after allowing Jetpac hosts. The plugin added:
Allow from ...
and broke the site.
Suggestion: have the user choose old/new version of Apache before making changes to .htaccess because recovery is PAINFUL unless the plugin is deleted from disk.
