After i use wordpress plugin for mobile web application “WordPress Mobile Pack”  i found that it caused duplicate meta description. Each of my link/permalink will be appended “?wpmp_switcher=desktop”, which indicates that instead of using the web mode display, we will use desktop mode display.

since it created miss configuration to meta description tag, i prefer to remove the plugin. but the affected links seem still the same. trying to understand this thing, i did these 2 things.

1. Clear the dns cache and browser history just to make sure these aren’t the thing that causes the problem.

2. Deleting completely any “WordPress Mobile Pack” in folder wp-include>>themes.

It seems working on my website, u can try to do it with yours too. hope this helpful for you.
