Hello, WordPress Gurus,
When checking html suggestion section of my Google Webmasters Tool, I am warned that hundreds of pages of my blog are having the duplicate titles. After expand the relevant item, I find the duplicated one having the ?cf_action=reject_mobile after the original URL.
Anyone knows where is the origin of this ?cf_action=reject_mobile?
Last year, I tried the WordPress Mobile Edition plugin, but not before long I disabled it and deleted it. I don't know if this ?cf_action=reject_mobile had something to do with that plugin?
