I removed the card option from the shortcode, ensured the single entry template option was disabled, and verified the Slim Plus template was the active template. There was no change to the look of the page.
I also assumed the card template had been altered, which is why I thought updating to the new version would refresh that template. Is that not the case? I only have WordPress access to the system this is hosted on, so my options are limited on how to address this; however, looking at the System Information tab under Settings it shows this:
— Connections Folder Permissions
Image Path Exists: Yes
Image Path Writeable: Yes
Template Path Exists: No
Template Path Writeable: No
Cache Path Exists: Yes
Cache Path Writeable: Yes
Could there be a permissions/path problem?
