Hello,

I could not enter your site as “Access denied”.

Please install the free Classic widget plugin if you have not done that yet.

Then try to regenerate “Regenerate the product attributes lookup table” in Woocommerce > Status > Tools: https://take.ms/LGpvf

In addition, please check Woocommerce > Settings > Product tab > Advanced tab and disable Use the product attributes lookup table for catalog filtering.

Let us know if the problem remains.

Best Regards
