Woocommerce cart not load

The ajax response starts with a byte order mark. Did you manually edit a PHP file of your theme by any chance?

Thanks for you answer, the files have been updated long time ago by a developper but not recently

Did you install or update a plugin recently?

…or edit wp-config.php?

I’ve same problem without any plugin, just with woocommerce, so I think is not this.
I hav’nt edit wp-config ??

You could try switching theme to see if it solves the issue.

Already done too, and same problem.

Unfortunately I can’t help you further then. The issue is clear; a PHP file contains the BOM but it’s impossible for me to know which one.

Good luck investigating this issue.

Thanks for your help, I’ll try to find it

I don’t know why, but it’s seems to works now…

Nice. An early christmas miracle!
