Your code is not making any difference for me, neXorianus. I fail to understand how replacing preg_split with explode will make this plugin ignore parameters. Would you care to elaborate?
I have the following URL: http://domain.no/158-some-old-url?adjust=1&from=0&iid=1480&pid=Domain-Article-Paragraphs.Domain-ParagraphText-Picture&r_n_d=42304_&x=512
What I need is to ignore everything after the ?, because the URL http://domain.no/158-some-old-url redirects just fine.
