AttributeError when pressing preview

[ligi]

I could install the plugin - then I selected 2 images and pressed preview. Then I got this error-page:

[raphaelm]

have you been able to fix that (unsure what your email refered to)?

[ligi]

No - but I just found the general settings where to upload the certs. Now I have to find out where to get these certs without creating a apple account.. But this should be treated as a bug regardless - if these files are not uploaded the preview should not be available.

[raphaelm]

I don't know if you'll find any valid certs without an apple account. :/ You can upload any RSA private key and X509 certificate compatible with SMIME, it just won't work on Apple devices then. (But if you create your esPass plugin, you can probably throw away all of this anyway.)
