Thanks for the feedback on my suggested mod to the newer plugin. It's hard to find solutions without being able to test...
Glad though that reverting worked for you. I'd say stick with 1.4.18 until one of the plugin devs fixes the incompatibility.
(I sometimes install Plugin Update Hider plugin on client sites when we are forced to use older plugin versions to keep critical functions - stops other admins updating the faulty plugin)
Fully agree with you about Google XML Sitemap plugin - prefer to use it as well.
Give me a moment - I saw something about the problem with the alternate language yesterday - stylesheet error - need to find it again
