I have been working with a filter plugin to filter products on our site also using Woo. I created a sidebar with the sidebar anywhere info I found in your documentation but the content in this area is not showing on the site. I turned off other plugins to test and still nothing. i can see the content, the short code coming up commented out in the area for the filter I set up but neither that content or just plain text is showing up on the page. I can show the page, but it is a staging site and to view the page I will need to white list an IP to actually get in and review the site.
I will try to upload an image of the rendered code, if someone needs into the site I can get your IP added to review if you can. This site is verified although not on my account, its a new employer I am working with, but they are verified just not on my account.
