While I haven’t directly encountered the redirect issue with my site, I encountered an issue where google webmaster tools/search console would receive a 500/unreachable error on all pages in wordpress after the 4.4 update, but only when NextGEN was enabled (regardless of if NextGEN is used on that particular page or not). This resulted in the site becoming unlisted from google until I disabled the plugin. While the pages seem to load fine in browser, the unreachable error from google only when the plugin was active suggests that I might be experiencing the same kind of issue. I’ve also tried updating, and it doesn’t seem to have resolved it.
