The Request Methods Filtered code should look like this code below. The code you posted above is not valid, but I assume that was just a copy and paste problem with your post. Since you have eliminated that BPS is causing the problem then you should do the standard WordPress troubleshooting steps next: deactivate all other plugins and test. Switch your theme to a WordPress theme and test. If the problem is with a WooCommerce setting or setup then I really cannot offer much help since I do not use WooCommerce and have very limited knowledge of WooCommerce. So you would want to contact the WooCommerce folks to get help for that.
# REQUEST METHODS FILTERED # If you want to allow HEAD Requests use BPS Custom Code and # remove/delete HEAD| from the Request Method filter. # Example: RewriteCond %{REQUEST_METHOD} ^(TRACE|DELETE|TRACK|DEBUG) [NC] # The TRACE, DELETE, TRACK and DEBUG Request methods should never be removed. RewriteCond %{REQUEST_METHOD} ^(TRACE|DELETE|TRACK|DEBUG) [NC] RewriteRule ^(.*)$ - [F]
