LiteSpeed Cache Plugin – PHP Warning: Cannot modify header information

[Jason]

Hi, I keep getting these errors from Litespeed:

PHP Warning: Cannot modify header information – headers already sent in public_html/wp-content/plugins/litespeed-cache/src/vary.cls.php on line 735

I checked that the litespeed folder is excluded.

I checked that WP_DEBUG is false in WP-CONFIG.

I’ve deactivated and reactivated Litespeed.

I’ve run the setup wizard again in BPS.

It also quarantined a heap of files but that seemed to get fixed after running the setup wizard again. Is there something else I can try? Thanks.

This is a known php error that is occurring with LiteSpeed lately.  The php error is not related to or caused by BPS.  Someone in the LiteSpeed plugin forum has reported this php error > https://wordpress.org/support/topic/warning-cannot-modify-header-information-headers-already-sent-33/.  The LiteSpeed plugin author will need to provide a fix for this.

Cool, thanks for your help.
