Wordpress LScache Plugin: Memcached::set() expects parameter 3
Last Updated on: Wed, 15 Apr 2026 00:00:02 Dears, I am getting the following warming on Debug: [08-Nov-2020 04:10:36 UTC] PHP Warning: Memcached::set() expects parameter 3 to be int, string given in /home/chilevapo.cl/public_html/wp-content/plugins/litespeed-cache/src/object-cache.cls.php on line 487 The only way to fix this until now was editing the file and replacing the variable $ttl by 360 or any number.
