   Overview Fullscreen Screenshot 2
   

I have a BIG sitemap that takes over 5 seconds to load

use a filter called ‘http_request_timeout’

I have multiple (language / domain) sitemaps, but I can only add one sitemap!

Use a sitemap index, pointing to all your (custom/sub)-sitemaps. Only add the sitemap main index file to the plugin. Do NOT have this in the custom file name:
warmcache-sitemap.xml OR warmcache. Use this for example: supersitemap.xml or my_cache_sitemap.xml

How to disable logging completely (for very large sites)?

Set a define in your wp-config (at the top, newline, after <?php ) with name MP_WARM_CACHE_NO_LOGGING_AT_ALL and value “yes”
Example
Please check https://plugins.trac.wordpress.org/browser/warm-cache/trunk/readme.txt#L38 DO not copy directly below due to the “curly quotes”
define(‘MP_WARM_CACHE_NO_LOGGING_AT_ALL’, ‘yes’);

How to run a cronjob?

Ask your webhost how to set up a get call using wget or curl. See Installation for instructions howmany times you should call the cronjob.

The plugin shows an error, it cannot read the XML sitemap

The fact that you are able to “see” the XML in your browser does not guarantee that PHP is able to read it too.

Consult your host about this, if that fails.

Sucuri / Audit log notifies about new posts beeing created

We use the hidden post type warmcache to store statistics. We also remove them upon each crawl.
Feel free to ignore creation of posts with warmcache.
See https://wordpress.org/support/topic/29-september-2016-update-causing-constant-post-update-notifications-from-secur/

I have set up the cronjob but the stats table on the plugin page remains empty.

@see The plugin shows an error, it cannot read the XML sitemap

How to override the 20 pages crawl limit

Set a define in your wp-config (at the top, newline, after <?php ) with name MP_WARM_CACHE_FILTER_LIMIT and value INTEGER
Example
Please check https://plugins.trac.wordpress.org/browser/warm-cache/trunk/readme.txt#L58 DO not copy directly below due to the “curly quotes”
define(‘MP_WARM_CACHE_FILTER_LIMIT’, 25);
