Hi Erin! IIRC, I specifically got the Post Type Archive page from Appearance>Customize>Menus and then I added it as one of the menu items. I am not able to do this anymore…not sure if it was inherent to Webcomic plugin or if I installed another plugin and then uninstalled it. Either way, I’m not sure how it is still working at this point.
I wanted to let you know that I took your advice and with the help of SpiderForest I got everything set up! Thank you for your help!
