No bogus, just a few lines of code, which are missing. Where exactly you had them before is hard to tell: They could have been inside the Apache server configuration or inside an .htaccess file.

So basically what you now have to do is set up short URLs as explained on that page: Manual:Short_URL/Apache. The .htaccess file for that has to be located outside of the wiki folder or with other words: In the parent of the parent of the images/ folder. It's all explained in Manual:Short_URL/Apache.
