@mrkunau plugin support says they have a potential fix that–if confirmed–they will release tomorrow (9/6/2023).

@j2fb we don’t have a confirmed fix yet. Plugin support made several changes to a dev version on our site, with a plugin version of 9.4.4.2. The site registered errors after their latest changes on Sept 1, but it’s possible that was due to caching and their dev changes resolved the issue. If so, I would expect an updated release of the plugin.

True, it’s a similar warning but a different plugin file reported as the cause. I’ll open a separate ticket. Thanks.

We’re seeing the same issue on a site running WordPress 6.3.1, PHP 8.0, Pixel Your Site version 9.4.4.

[29-Aug-2023 15:44:54 UTC] PHP Warning: Cannot modify header information – headers already sent in /home/[username]/public_html/wp-content/plugins/pixelyoursite/includes/class-pys.php on line 194

Done, thank you!

Thanks for your reply.

When I add that snippet to functions.php in the active theme, Query Monitor reports these missing handles on the front end:

• prettyPhoto
• prettyPhoto-init
• woocommerce_prettyPhoto_css

I can ignore the warning if it does not cause issues with the site.
