Hmmm, yes, deactivating that works.
Although I must say I am a bit confused as to why Super RSS Reader – PRO is the first plugin that has caused that issue with block-options.
Anyway, I can live without block-options, so it’s all OK 🙂 Problem solved – for me anyway.
But now this works… there is one more thing!
Would there be any way to add a filter for <pubDate> in Super RSS Reader – PRO? Basically allowing feed options to be constrained by date? I am using your plugin as a kind of quasi live blog – and having a date filter would be super useful!
