For each blog post we got two urls one with easyblog/entry other using category alias

For eg;

http://rmsrecruitment.com/easyblog/entry/18th-september-2015-competition-time-taking-on-the-robots

http://rmsrecruitment.com/lucy-s-diary/entry/18th-september-2015-competition-time-taking-on-the-robots

We want only one unique url for a post. Please let us know what we have to do for that

Thanks
