I haven't used this plugin for other WP versions so I'm not quite sure if I got the installation right the first place. I made a page to link to the directory, which showed up OK. The categories looked ok and imported links seemed to be in their correct categories. However, when I clicked any links inside the plugin, I was redirected back to the front page. I tried changing the page URL (from link-directory to links) but it didn't seem to help the cause.
