Changes are made at your own risk and are not guaranteed to work. Always make backups of the database and files prior to implementing hacks. Make a special backup of the file and/or template you are modifying so that you can roll back quickly.
Hacks are dangerous and can cause your site to stop working. They make later updates to ExpressionEngine more difficult; you should track your hacks for post-update re-implementation.
Most hacks are unnecessary, please review the Development Documentation for information on expanding ExpressionEngine via Modules, Extensions, and Plugins.
Hacks are never officially supported.
Question:
Is there an easy way to update the database, so all my old entries will immediately track changes?
Answer:
update exp_weblog_titles set versioning_enabled = "y" where versioning_enabled = "n" and weblog_id = "1"
This will update your entries that are in weblog #1.
