Where are the settings of the plugin?

There is no settings page. This plugin is designed to be small and simple.

How can I change the content or layout of the maintenance page?

This is not intended by design. Please use another solution if you want a custom maintenance page.

How can I submit a new translation?

Please visit the plugins page at WordPress Translate.


Super simple

This is a simple solution I looked for. The site I have it installed, it uses two languages with the help of Polylang. Could you consider adding the same browser language detection and build it in your plugin?

Simple and translatable

Does what it says and does it in a simple and perfect way. Also, it's i18n ready and can therefore be translatable to other languages. Not all the plugins this simple enable translation. Congratulations. And thank you for sharing your work. PS: I added Portuguese (Portugal) translation, for both pt_PT default and pt_PT_AO90 variants.

Nice plugin

Simple, easy, effective. The code shows that the plugin clears any caches a site might be using, which is important.

nice one

Better to use this one than to edit .htaccess or functions.php Im gonna use this one for my personal blog.
