Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi dear Litespeed Support, I get the following errors every few seconds after upgrading to the newest / recent version: [26-Nov-2022 12:30:39 UTC] PHP Warning session_set_save_handler(): Session save handler cannot be changed after headers have already been sent in xxx/public_html/wp-content/plugins/geotargetingwp/vendor/ericmann/sessionz/php/Manager.php on line 133 [26-Nov-2022 12:30:39 UTC] PHP Warning Cannot modify header information ? headers already sent in xxx/public_html/wp-content/plugins/litespeed-cache/src/vary.cls.php on line 735 I dont know if the error messages are linked so I post both (the second one is a litespped error) May you help what we could do? Thanks in advance.
