Asset Manager Not Opening When Clicking 'Select or upload an image' (Runway)

  • Hi

    I've got a client site which has been working fine, but has now developed a bug (not sure how). It's a Runway build, and all of the 'Select or upload an image' links have stopped working. The asset manager does not open and there are no errors to see in the browser console, so I'm at a bit of a loss as to how to best to troubleshoot the issue. I've just updated the installation to 3.1.5, and the diagnostic report is as follows:

    Any suggestions? Thanks!
