Hi Emilio,
thanks for your response ! The issue is not causing any functionality issues I was just weirded out why all the sudden that array error showed up and why I can only see it on mobile devises. I double checked my php files and couldnt see any obvious reason that couldve caused that error.
I solved the problem first with adding the code into my wp-config.php file – what seemed worked fine – but decided now to create new pages in my store and use the woocommerce shortcuts to show my choosen product categories. Just in case that the main issue behind the error could cause some issues.
Thanks again for your help !
I`m still stuck with this issue. Im thankful for any kind of help or tipp.
Okay, I will do that! Thanks for your quick response. I appreciate that.
