Again, CWP doesn't add or remove modules automatically. And this latest update just added some reports and the latest PHP versions to build.
UNLESS you rebuild Apache, then everything goes back to defaults.
You have to make these changes manually via the httpd.conf file.
But looking at our servers the mod_rewrite is active by default.
You can check the Enabled/Disabled modules by:
WebServer Settings -> WebServer Conf Editor -> (/usr/local/apache/conf) tab -> Click Blue Edit button to the right of httpd.conf
Then Ctrl-F to search for 'mod_rewrite'
You will see the line:
LoadModule rewrite_module modules/mod_rewrite.so
If yours, for some reason starts with a #. Delete the comment marker (aka #)
Save changes, and restart Apache.
