Can’t upload image

The error is like this. https://ibb.co/gr4QNbd

Can you please test upload of images now? It should be fixed.

It’s working now. Can I know what’s the issue?

One issue from the diagnostics tab. https://ibb.co/LnZZv6j

The problem was related to the configuration of AWS server for upload of images.

The screenshot from you diagnostics tab shows that your theme doesn’t implement WC Slider library. Please see more information here: https://woocommerce.wordpress.com/2017/02/28/adding-support-for-woocommerce-2-7s-new-gallery-feature-to-your-theme/

You theme might be using some other library for sliders. If this is the case, you can safely ignore this error indicator.
