The documentation for
The directives provided by mod_access_compat have been deprecated by mod_authz_host.
So as long as any deprecated
Deny directives are removed from Apache configuration files, it's safe to disable the module.
sudo a2dismod access_compat
If you've missed of the old style directives in your configs, Apache will fail to restart and point to the instance of the old syntax:
AH00526: Syntax error on line 23 of /etc/apache2/sites-enabled/google.conf: Invalid command 'Order', perhaps misspelled or defined by a module not included in the server config Action 'start' failed. The Apache error log may have more information. apache2.service: Control process exited, code=exited, status=1/FAILURE
Just remove the offending directives and restart Apache again, and repeat until the restart succeeds. See the 'Access Control' section of the Apache 2.2 -> 2.4 upgrade guide for details on how migrate your configs to the new syntax.
