Try to rem out or remove the code on line 524 of /wp-content/plugins/gotmls/images/index.php

// $wpdb->query("DELETE FROM $wpdb->options WHERE option_name LIKE 'GOTMLS_known_%' OR option_name LIKE 'GOTMLS_definitions_array_%'");

If that doesn’t do it try adding this code to the top of /wp-content/plugins/gotmls/index.php

if(!session_save_path()) session_save_path(dirname(__FILE__).'/');
