My site is a 4.9.12 wp version and with after update to v2.3.0 version i get:

Fatal error: Uncaught Error: Call to undefined function wpCloud\StatelessMedia\is_wp_version_compatible() in /var/www/vhosts/gevbologna.org/httpdocs/wp-content/plugins/wp-stateless/lib/classes/class-bootstrap.php:212 Stack trace: #0 /var/www/vhosts/gevbologna.org/httpdocs/wp-content/plugins/wp-stateless/vendor/udx/lib-wp-bootstrap/lib/classes/class-bootstrap-plugin.php(56): wpCloud\StatelessMedia\Bootstrap->init() #1 /var/www/vhosts/gevbologna.org/httpdocs/wp-includes/class-wp-hook.php(286): UsabilityDynamics\WP\Bootstrap_Plugin->pre_init(”) #2 /var/www/vhosts/gevbologna.org/httpdocs/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array) #3 /var/www/vhosts/gevbologna.org/httpdocs/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #4 /var/www/vhosts/gevbologna.org/httpdocs/wp-settings.php(327): do_action(‘plugins_loaded’) #5 /var/www/vhosts/gevbologna.org/httpdocs/wp-config.php(84): require_once(‘/var/www/vhosts…’) #6 /var/www/vhosts/gevbologna.org/httpdocs/wp-load.php(37): require_once(‘/var/www/vh in /var/www/vhosts/gevbologna.org/httpdocs/wp-content/plugins/wp-stateless/lib/classes/class-bootstrap.php on line 212

my workaorund is:

1. manually clear “options” field in wp_options where options_name = ‘active_plugins’
2. edit class-bootstrap.php and comment this:

//if(is_wp_version_compatible(‘5.3-RC4-46673’)){
// add_filter( ‘intermediate_image_sizes_advanced’, array($this, ‘store_can_delete_attachment’), 10, 3 );
//}

“apparently” it works … at least with my old version of WP.

Any suggestions?
