Thank you for your reply.

As you can read in my previous post:

SiteGround Optimizer 7.2.8
PHP 8.1.3
FPM served by Apache
nginx proxy

The issue is that the apache_response_headers() (a PHP function) does not exist on my system and disabling themes or other plugins won’t solve that.

It would be better if you checked if the function exists

if (function_exists(‘apache_response_headers’)) {
//loop here
}

We have released a new version for environmens where this method is not supported.

You can update the plugin and verify the results on your end.

Thank you again for the reports!

Best Regards,
Elena

hello
thanks

now yes, with the new version, the problem has been solved.

Hi. I am getting:

Cannot modify header information – headers already sent in /public_html/wp-content/plugins/sg-cachepress/core/File_Cacher/Cache.php on line 142

Just updated to

Running Linux, LiteSpeed PHP version 7.4.33

Hello @katmacau,

We have not received similar reports after the latest plugin update to version 7.2.9 and the mentioned error does not seem to be related to the issue originally reported in this thread.

Please follow the forum guidelines and start your own separate topic so we can take a closer look at the issue you are experiencing.

Best regards,
Dimo
