Good morning Igor!
Thank you for your quick feedback. We have already processed the message you linked to several times. So far without success.
Would it be possible for you to take a quick look at our wp-config.php?
The error/warning only occurs with plugin updates from WooCommerce and Updraft. All other updates run without this message.
best regards

Hi @nick7766,
Would it be possible for you to take a quick look at our wp-config.php?
You can post the contents of them using something like: https://justpaste.it/ – be sure to leave out all sensitive info like your database access and WordPress salts. https://d.pr/i/pj8PZz

Good morning Con!
Thank you for your help. The error occurs in Load.php line 280 and not in wp-config.sys. Therefore I shared the load.php with you.

Hello,
Thanks for sharing the file!
I’ve compared it with the load.php in a local install, and it’s exactly the same. There’s no issue with that file. Notice that the error does not say there’s something wrong with load.php, the error is pointing to line 280 as the reason why the system can’t perform what’s being asked of it – “Cannot modify header information”.
Which means some plugin or the theme in your WordPress site might be causing this issue. There’s no easy way to troubleshoot, but I would suggest you consider performing a conflict test to see if the error shows up when you activate a specific element.
Hope this helps!
So I will do a conflict test at our staging.
thnx for helping Paulo
best regards
