Just trying to resolve an issue that I /think/ started to occur with the most recent Marketpress release.
Head to this example product page:
Click "Add to Cart" and you arrive at a page that looks like the screenshot excerpt attached. The item IS added to the cart, so that aspect is working it seems.
For some reason the browser isn't redirected through to the original page. Has anyone else seen this?
I am reasonably sure it didn't happen before the latest release, however I hadn't done much testing before the new version became available.
