Surbma

CherryPick Studios

With Offline Mode, features that do not require a connection to WordPress.com servers can be activated.
This plugin is using the jetpack_offline_mode filter to enable the Offline Mode. If you are familiar with ftp and file edit, you can also add the <code>define( 'JETPACK_DEV_DEBUG', true);</code> to the wp-config.php file. Make sure you add it before the <code>/* That's all, stop editing! Happy blogging. */</code> line.
This plugin also checks if the Jetpack plugin is already activated, so it is safe to use this plugin.

Jetpack automatically disables its Open Graph tags when there’s a known plugin that already adds Open Graph tags, which is good. Sometimes, though, you might want to use Jetpack’s version instead. Even if you disable the tags in the conflicting plugin, Jetpack won’t add Open Graph tags without being told to do so.
This is great for when you want to use the awesome WP SEO by Yoast plugin or others like All-in-One SEO, but, for whatever reason, would like to use Jetpack’s OG tags instead.
