Companion Auto Update


Keep your website safe!

We understand that you might not always be able to check if your wordpress site has any updates that need to be installed, especially when you maintain multiple websites keeping them up-to-date can be a lot of work.
This plugin enables background auto-updating for all plugins, all themes and the wordpress core (both major and minor updates).
We give you full control over what is updated and what isn’t, via the settings page you can easily disallow auto-updating for either plugins, themes or wordpress core.

Available settings

Full control, that’s what this plugin is all about. We offer settings to enable or disable automatic updating for plugins, themes, wordpress core updates (both minor and major can be changed separately) and for translation files.

Know what’s happening

We want you to know what’s happening on your website. This plugin offers settings for various email notifications. We can send you an email when an update is available, when a plugin has been updated or when wordpress has been updated.
But if you don’t want to recieve emails about this you can still log in and view the changelog to see what happened.

Advanced Controls

You can control auto-updating per plugin via the plugin filter.
For example: If you have Woocommerce installed but you do not wan’t to have it auto-updated you can now disable auto-updating for Woocommerce only, so your other plugins will continue to be updated.


By default the updater will run twice a day, but you can change this to every hour or to daily. When set to daily you can even set the time at which it should run, this way you can make sure that it will not overload your server by letting it run at times with less activity. The same settings can be set for notifications.

Can I disable auto updating for certain plugins?

Yes. You can control auto-updating per plugin via the plugin filter.

I’m using cPanel and auto-updating doesn’t work

A few years ago cPanel added a line by default that would disable auto-updating. According to cPanel this can be fixed by removing the line “AUTOMATIC_UPDATER_DISABLED” from your wp-config file.

My theme by Elegant Themes is not updating

For some reason this plugin seems to have trouble with updating themes by Elegant Themes on some installs. I’ve reached out to Elegant Themes and they couldn’t help me. They said that if you’re experiencing problems with it you should contact them and they would help you with it.

I tested it as an alternative to a well known plugin and was surprised to see that Companion Auto Update has more features and is more complete.

Plugins disconnected from the update - still hysterically write "need to update". Messages are not disconnected, it is annoying. But WordPress does not automatically update, alas ... Неплохо, но есть что исправить. Плагины отключенные из обновления - все равно истерично пишут "надо обновить". Сообщения не отключаются, это раздражает. А вот WordPress не обновляет автоматически, увы...
