Multisite support added in v0.6!
Notice: this plugin will not have further major updates. If interested in new features, please upgrade into this compatible replacement: https://wit.rs/wp-plugins/wit-custom-output 
After uninstalling the WPCHTMLP and installing WIT Custom Output, your old custom pages will still work, but with better interface, more features and regular updates.
WP Custom HTML Pages plugin has two functionalities:
1 – Create a custom HTML document output at a custom permalink address, completely bypassing WordPress templating. This is useful in cases when you just want to output some HTML without uploading the page to the server.
2 – Create a shortcode which outputs your custom HTML.

Display full custom HTML on custom permalink address, or put it inside content as a shortcode.

Semio Design

Pierre-André Boissinot

When you use the WordPress editor to insert a media in the content field it stores a reference to the absolute path. 
So if you change the location of your site (by switching from staging to production environment for example) all your paths will be incorrect. 
This plugin stores relative pathes in the db instead of an absolute path. 
Beware: this plugin must be activated BEFORE inserting a media into the content field. It has no effect on the medias stored before the activation. 
It’s mostly based on the WP_SITEURL constant which should be defined in the wp_config.php file. If this constant isn’t defined it uses the “siteurl” option value instead. 
If the plugin detects that you access the website from another location than the “siteurl” defined initially it can correct most of the wrong urls in the database.
Localisation of the plugin into french.

Simple Relative Content

This plugin makes all attachments urls stored in database relative to the WP_SITEURL url.
