Welcome to the Q&A Forum

Hi Benjamin, Although there is a possibility that your WordPress redirect plugin is causing this issue, it would be hard to tell without having access to the CMS. Often times a plugin will have a box that's checked somewhere that might cause something weird to occur. However, I doubt this is the case. To answer your question, I would do this in the htaccess file although I would be cautious and test it first. Here is a write-up with someone who had a similar issues (he goes into details about his solution). Hope that helps!
