Ah found that is there is special forum for that plugin and asked there 🙂
Hey @ckadenge ,
thank you for your quick response. 50 plugins later i found the one causing the error.
Its “Advanced AJAX Product Filters for WooCommerce” – Do i have to reach out to the developer or do you think you can help there too?
Best,
Johannes
