I did everything they said in the update tutorial.
Point your browser to your Control Panel, and follow the on-screen instructions to update ExpressionEngine.
At this point, no “on-screen instructions” come up. I just see the website and control panel like nothing happened. Version still displays 2.7…..
Could it be because I renamed system, admin.php and index.php?
Shouldn’t the tutorial mention what to do in this case seeing how it’s an officially recommended security measure?
