P.S: My plugin is not deleted.
Hello, I’m having the same issue and they started on 19th February 2016.
Google Analytics crawl errors is showing a very high increase of “URL Errors”.
Basically, it’s complaining about 250+ links like: “wp-admin/admin-ajax.php?action=wti_like_post_process_vote&task=like&post_id=505&nonce=7c7176f74f” in my page, changing only the post_id and nonce on the urls.
They are returning code 302 to Google.
Google says: “Google found a redirect on this page, but it didn’t point to anything, so the Googlebot couldn’t follow it. Make sure that all of your redirects are valid and not empty.”
Thanks,
Rodrigo Jorge
