The code quality of this script is very poor. I have just finished spending approximately twelve hours fixing bugs and customizing the script to get it how I want. I followed all the instructions properly to set up the script on my shared server using php 5.3, but the result was a blank white screen. It was then that I started to find bug after bug. The code needs to be updated. It is a shame because if the developer updates the code and is committed to improving the script, it could be a fantastic product. But there were so many bugs. For instance installing the script to a specific folder causes the script to break. Then there is the fact that the users cannot delete the bookmarks they set. Then there were problems with deprecated code in php. But after I spent approx. twelve hours fixing the bugs and customizing the site, it is satifactory. Therefore I can only give a two star rating because the only reason it worked for me is because I am skilled in programming. If someone buys this script and they are not skilled in programming, they are likely to run into a lot of problems.
