PHP error in debug.log

Hello,

I am waiting another few days before giving you access to a staging site (both you and WPML have released updates which may have solved some of the PHP errors).

However I have a new PHP error showing on the shop and category pages. Do you have any idea what this could be? See below. Thanks.

Notice: wp_woocommerce_session_02480d41d944f1daa715e22d736590d2 cookie cannot be set – headers already sent by /home/xxxxxxx/public_html/xxxxxxx/wp-content/themes/woodmart/header.php on line 5 in /home/xxxxxxx/public_html/xxxxxxx/wp-content/plugins/woocommerce/includes/wc-core-functions.php on line 892

Hello,

I have gone ahead and created a staging site for you to look at. My development domain is suffering from 500 errors whilst working in the backend, and the index.php page is having 1000’s of executions which is causing all my other sites on my hosted environment to go down. There is some issue.

These PHP errors I showed you before are being repeatedly produced (I have listed them again below). You can also check the debug.log yourself.

Could I please ask you to access the staging site I created (copy of live site with the issues), and see if you can help find the problem? Thanks in advance.

Hi Eric,

I have given FTP access in private content.

Thank you

Thank you again,
Can you tell me what PHP errors that will fix? There were 5 or 6 different errors.

OK. So the other errors on woocommerce/includes/wc-formatting-functions.php on line 871 / 872 / 873 – would you think they are the result of a WooCommerce problem? I need to try clear those too.

Thank you.

OK that’s great news. Thank you.
Any ETA for that update? Days or weeks?

Hi Eric,

I am inclined to think it was these PHP errors which was overloading our resources and causing the occasional 500 server errors (with the index.php being accessed thousands of times as I showed you in the screenshot). Would you agree with that?

You will have better knowledge about that than me. Thanks

Yes the 500 errors and server overloading seemed to occur during editing of certain pages etc in the backend.
