Forking the WP-Maintenance-Mode plugin…
I went to work on an “un-released” WordPress site of mine the other night and discovered that was displaying a blank page! It was displaying a title and summary of the site courtesy of the “WP Maintenance Mode” plugin. Turns out that this particular plugin has been handed over to a new maintainer and recently updated.
The recent update actually looks very good and the interface is a big improvement on how it used to look, however they removed all the original templates that were the reason I liked the plugin (which, being their project, is their prerogative).
In keeping with the Open Source spirit, I simply forked the code for the plugin and rolled it back to the last point before the templates were deleted. For anyone else that liked the old templates, feel free to grab the old version from GitHub here: Caffeinated-Maintenance-Mode.
