Invalid RSS Version: x.y
Explanation
Released versions of RSS include:
RSS 0.93 and RSS 0.94 were never finalized.
RSS 0.90
and RSS 1.0 have a completely different XML structure, and in particular, no version attribute.
Solution
In most cases, simply changing the version attribute to 2.0 is the simplest fix.
If, however, you actually are intending to produce a valid RSS 1.0 feed, consult the specification linked above for guidance.
