I have just upgraded my macOS 26.1 install of MAMP to version 7.3. Cool, right? Partially.
It seems that any/all projects with an .htaccess file that have RewriteEngine rules set chokes the works.
Checking the error logs in /Applications/MAMP/logs/apache_error.log show the following lines:

The core error message being:
.htaccess: Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
This stinks. What can I do to fix this?
