My upcoming blog has many plugins. When I activate the ones I need, except Polylang, the permalink I want to use (Day and Month) does work. When I activate Polylang, URL/page/xxx is available yet it no longer works even though I can select it. It does take me to the homepage but not to the page number I'm supposed to. I thought at first it might be W3TC but I haven't use it in the last two weeks. So far I'm using: About.me, AdRotate, Advanced iframe, Akismet, Auto Post THumbnail, Google Analytics, Jetpack, JW Player plugin for WP, NextGen Gallery, SEOPressor, TimThumb Vulnerability Scanner, WordPress Importer, Wordtube, and WP Google Fonts. I've turned off all the plugins, activated Polylang, and the pagination does work, though I only get the latest posts, or basically the same as the homepage or page 1. What's going on?
