Override of templates

That’s quite strange. What templates are your overriding? Can you post your system status report here as well: https://www.ads-software.com/support/topic/before-posting-gather-the-following-details

Also try temporarily switching back to the WordPress Twenty Sixteen Theme, or Storefront, and disable all plugins except for WooCommerce. If that resolves the issue, then slowly re-enable features until you find the one that’s causing the conflict.
