PHP Warning Cannot modify header information

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.
