I'm getting very weird 301 crawling errors in Google Webmaster Tools since 21st of March. I have no idea about the reason behind these errors, as they have a very uncommon and nested link structure.
The website I'm talking about is http://mafia-daily.net/, and one of these strange links looks like this:
Seems to be randomly created, consists of different pages, posts, categories and attachments. Every single link part is separated by two pipes || (= %7C).
The only thing I have changed since the 21st of March was a little tweak in the functions.php of the theme, but I have reverted back to the old version and I'm still getting the errors. Also I'm using the UberMenu Plugin for a few days now, but it's not creating links like the above.
I've got more than 200 of these errors by the time of writing, getting more every day. Don't know where Google can find these links, I have absolutely no clue.
Did someone of you guys see something like this before?
Any help would be greatly appreciated.
Thanks and happy Easter,
