The export feature works for new projects
Once a project has been exported a few times it stops working. No error reported.
Which version of rib did you use? Online, master branch or preview2?
Can you describe a little more about how to reproduce the problem?
Its difficult to reproduce. Thought it might be a known issue. Will reply when I can reliably reproduce it.
Turns out that this was caused by adding an image element and giving it a src value like "/images/example.jpg".
Good to know
Thanks for provide the root cause of this problem. Maybe you can file another issue about exporting a project with wrong image src?
