Cannot import crl certificates

[doktornotor]

Dunno what you uploaded where, but you certainly uploaded nothing here.

There is seriously is no point in debugging some "crash" you provided zero information about on the forum and continue refusing to do so.

The missing + button on CRL is by design, not a bug, as explained by multiple people multiple times. What you doing is not a valid PKI workflow. If you do some reading on the topic, you'll discover things such as CRL distribution points, which are embedded in certificates (X.509 v3 extension). Now try to get your workflow working with that.
