I had noticed that Avisio was messed up after updating WordPress, so I ended up here after googling "Avisio 404", since all my links were pointing to 404 errors.
Thankfully I realized I wasn't the only person that had the problem after reading a few threads on this forum, and was pleased to see that you guys made an update to address the 404 problem that was occurring (thanks!)
The majority of the 404 errors are now gone since I updated Avisio to the latest version, but there is still like two links that are not working correctly.
The website is http://jmosesart.com --- on the very top navigation you will notice the "Portfolio" link, which when pressed works as intended, but if you click on the other two links in the "Portfolio" dropdown menu ("Art For Sale" / "Commissioned Art"), it leads to a 404 error, even though my permalink in edit mode shows that's the true URL. I have refreshed my permalink settings in WordPress after the Avisio update as well.
Any thoughts on how to get this fixed? For some reason I think it's something really simple being overlooked. Much appreciated.
