 * **Just saw there is another thread started around this subject. Sorry for double
   post.**
 * Not sure it’s from PHP7 or just other plugins but I get this error when I activate
   the Warm Cache plugin:
 * The plugin generated 651 characters of unexpected output during activation. If
   you notice “headers already sent” messages, problems with syndication feeds or
   other issues, try deactivating or removing this plugin.
 * I get these warnings after I activate it:
 * Warning: Declaration of warm_cache::addPluginSubMenu() should be compatible with
   mijnpress_plugin_framework::addPluginSubMenu($title, $function, $file, $capability
   = 10, $where = ‘plugins.ph…’) in /srv/users/serverpilot/apps/wp/public/wp-content/
   plugins/warm-cache/warm-cache.php on line 24
 * Warning: Declaration of warm_cache::addPluginContent($links, $file) should be
   compatible with mijnpress_plugin_framework::addPluginContent($filename, $links,
   $file, $config_url = NULL) in /srv/users/serverpilot/apps/wp/public/wp-content/
   plugins/warm-cache/warm-cache.php on line 24
 * Also in Console I get this:
 * Mixed Content: The page at ‘[https://DOMAIN.COM/wp-admin/plugins.php?error=true&charsout=651&plugin=wa…cache%2Fwarm-cache.php&plugin_status=all&paged=1&s&_error_nonce=f1b17e4788&#8217](https://DOMAIN.COM/wp-admin/plugins.php?error=true&charsout=651&plugin=wa…cache%2Fwarm-cache.php&plugin_status=all&paged=1&s&_error_nonce=f1b17e4788&#8217);

 * **In addition: it has been tested on PHP 7.x and works fine**
