I updated the plugin to 2.8.2. The issue I mentioned here is solved. Thank you.
However, the initial problem for which I have resorted to the newer versions is still there. When there are more than one pages of links under a category, i.e. the links are ‘paginated’, when I try to go to another page under that category, the link category displays the default link category instead of going back to the second page of selected category. (should i put up a new topic for this?)
