- Go to https://glitch.com/ (must be logged in)
- Right click on your cover (the thing behind your 1x3 project list)
- Click inspect element
- Look for
<div class="cover-container undefined" style="background-image: url("https://cdn.glitch.com/55f8497b-3334-43ca-851e-6c9780082244%2Fdefault-cover-wide.svg?1503518400625");"></div>
- There is an undefined in the class name [confirmed to exist in both normal and custom cover]
Hahah, thanks! Good catch
Fix’d and deployed.
