Some plugins, themes, and hosting providers are known to conflict with some of the features implemented in Jetpack. Until these conflicts are resolved, you can check this list to find out what to do.
Facebook Pages associated with Facebook Business Manager
Facebook Pages managed under Facebook’s new Business Manager are not able to be used with Publicize currently.
iThemes Security (formerly Better WP Security) and BulletProof Security
These plugins can block access to your site’s XML-RPC file. This file is used by Jetpack to connect to WordPress.com, and must be accessible at all times. You will consequently need to configure iThemes Security, Better WP Security, and BulletProof Security to make sure that your site’s XML-RPC is publicly accessible.
W3 Total Cache
There are known issues with the Minify engine in W3 Total Cache and many other plugins, including Jetpack. If you experience issues when the Minify engine is activated, try deactivating it to see if it helps.
Antispam Bee, Spam Free WordPress, Bad Behavior, WP-SpamShield, CommentLuv, Anti-spam
These plugins are currently not compatible with the Jetpack Comments module.
Users have reported that when using the Subscribe2 plugin, Jetpack Comments can disappear from the Settings page. To fix this issue, you need to go to your Subscribe2 > Settings page, click on the “Registered Users” tab at the top, and scroll down to the bottom where you will see “Display checkbox to allow subscriptions from the comment form:” – make sure to set that option to “No” and your Jetpack Comments module will come back. Example:
Cleaner Gallery / Hybrid themes
If you use the Cleaner Gallery plugin or a theme including this functionality, you won’t be able to use the Carousel and Tiled Gallery modules on your site. To solve this conflict, you can install this small plugin to deactivate Cleaner Gallery.
The ComicPress theme is not compatible with Jetpack’s Mobile theme. Comics published via ComicPress cannot be accessed from the Mobile Theme.
CloudFlare’s Rocket Loader
There are some known issues with contact forms on sites using WPML not sending emails to notify site owners, however the contact form submissions will still be recorded in the Feedback section of your site’s Dashboard.
Sites using HTTPS
Do you use an SSL certificate on your site? If you’re having trouble connecting Jetpack to your WordPress.com account, try adding the following to your site’s wp-config.php file:
define( 'JETPACK_SIGNATURE__HTTPS_PORT', 80 );
This works on hosts that have SSL terminate on a reverse proxy and the server itself is still listening on port 80 or something similar.
Alternatively, you could add this to your wp-config.php file (please not both!):
$_SERVER['SERVER_PORT'] = 443;
This sets the server port to 443 for the whole site.
If none of this helps, we’d suggest checking the status of your domain’s SSL certificate.
There is a known issue with the WP-EMail plugin and Jetpack Subscriptions. If you have this plugin active, it will not let people sign up using the Jetpack Subscriptions Form.
Custom CSS and WP Engine
Custom CSS will not be applied to visits by search engine bots on WP Engine sites due to a rule on their server to prevent bots from loading dynamic content. This can impact users, for example, whose Custom CSS modifies the layout to meet Google’s mobile-friendly designation. To work around this issue, either contact WP Engine support asking to remove the “Redirect Bots” option or add the Custom CSS directly to your theme’s style.css.
Pinterest Pin It Button On Image Hover And Post plugin
Infinite Scroll does not work when using the Pinterest Pin It Button On Image Hover And Post plugin.
Windows Cache Extension for PHP
We have some reports that this extension for Windows IIS servers can prevent Jetpack from connecting properly to WordPress.com. If your site is on a IIS server, please try disabling this extension if you are having difficulty connecting Jetpack to WordPress.com.
