[SmartCrawl Pro] Parsing error on split sitemaps

I noticed that something was up back when the split sitemap option became available. But, Google search is now alerting to the error. (If I recall, it didn’t throw an error before… only failed to parse & fetch newly added sitemaps)

This is happening on a few of my sites that use the Split Sitemap feature, so I’m pretty sure that this isn’t localized.
