I recently added a minor update to both the Aspire 2.0 theme as well as the Aspire Collections plugin. If you’re still having issues, try and download the latest version and upload those to see if it works.
I’ve tested the updates on multiple servers, both local and a live demo site.
Here are the updated versions –
Aspire Theme 2.0.1
Aspire Collections v1.0.1
I haven’t seen anyone mention any issues, but I added a couple updates to ensure it works with your setup.
Please let me know if this helps.
