WP Rocket compatibility: so-widgets-bundle is executing rocket_clean_domain and rocket_clean_minify 4 times after updating a post. This causes server problems in some cases about so-widgets-bundle

Hi Sandy,

Thank you for providing a copy of the log, and your detailed response. I've had a look at the provided logs and it doesn't appear this issue is related to the Widgets Bundle. It appears to be related to Page Builder. Specifically, the below lines in the provided log appear to highlight what's going on:

9) /nas/content/live/k9uchstaging/wp-content/plugins/siteorigin-panels/inc/admin.php(1015): apply_filters('widget_update_c...', Array, Array, Array, Object(SiteOrigin_Panels_Widgets_Layout))
10) /nas/content/live/k9uchstaging/wp-includes/plugin.php(205): WP_Hook->apply_filters(Array, Array)
11) /nas/content/live/k9uchstaging/wp-includes/class-wp-hook.php(326): rocket_widget_update_callback(Array)
12) /nas/content/live/k9uchstaging/wp-content/plugins/wp-rocket/inc/common/purge.php(27): rocket_clean_domain()

Here's an outline of what's happening here:

Page Builder is updated.
We [trigger widget_update_callback here](https://github.com/siteorigin/siteorigin-panels/blob/develop/inc/admin.php#L1015).
WP Rocket picks up on this through `rocket_widget_update_callback`.
WP Rocket then fires `rocket_clean_domain`

WP Rocket is clearing the site cache when the user updates a widget in Page Builder. This makes sense based on traditional WordPress Widget usage (basically, all widgets are in global Widget areas), but Page Builder (and other plugins) add them to pages so a widget update can occur outside of that context. In this specific instance, the WP Rocket callback is triggered multiple times presumably due to there being multiple widgets on the page. Whether that's something we should prevent, or you should on your end isn't clear. Open to ideas, and happy to work with you on this.

Regarding the rocket_clean_minify you mentioned, that code is run when 'upgrader_process_complete', 'switch_theme', and 'activated_plugin' actions. This is to allow for the Widgets Bundle CSS cache to be safely cleared. We make use of rocket_clean_post when clearing it on a post by post basis.

Kind regards,
Alex
