PHP error in debug.log

Hello,

I have the following PHP errors which are produced many many times each day in my debug.log. I need to find a fix for all of them. Can you help with any of them? My site is occassionally suffering from 500 server errors which could be down to some of these:

Hello,

Are you able to provide us your FTP access so we could troubleshoot it and provide you with a solution?

Regards

Sure not a problem. Let me first set up a staging copy of the site so you can go in there. It might not be before tomorrow when I can do that.

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

Have a lot of “cookie cannot be set – headers already sent” in wp-debug as well.

Hello,

This notice sometimes happens when our sessions conflict with WooCommerce ones. You can ignore these notices since they are harmless. Currently, we didn’t find a way to use WC sessions and avoid this notice.

Kind Regards

OK we will ignore then that error if it is harmless and doesn’t effect resources. Thanks.

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.

Hello,

Please, provide us your FTP access so we can log in and check this on your side.

Thank you in advance.

Hi Eric,

I have given FTP access in private content.

Thank you

Hello,

We found the problem and fix it in the next update.

Kind Regards
XTemos Studio

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

All that relate to our theme

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.

Yes we checked these errors should disappear too.

Kind Regards
XTemos Studio

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

Hello,

We plan to update in a few weeks but now we can’t say the exact date.

Kind Regards

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

These errors appear only in the admin panel when editing content with some elements. They are not called on the frontend and should not load the site.

Kind Regards
XTemos Studio

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

Perhaps the reason is caused by these errors, we will definitely fix them in the next update. I hope this helps you.

Kind Regards
XTemos Studio
