I tried and tried, and tried again. And finally decided to ditch a component I paid $85 for, because it breaks after other component installations. My purpose for purchasing the software was to allow my clients access to project status, task, calendar, and file upload. After trying their online demo I decided to purchase the product. Mistake!
1) There are plenty of free and open applications that do the same job and better Project Pier, SugarCRM, and Achievo just to name a few. I picked jprojects, because it was a built specifically for Joomla!
2) Clients cannot view the calendar on the frontend.
3)I installed rokbridge and clients could no longer view project information on the frontend (No_Auth message). Thinking that it maybe related to rokbridge I uninstalled the application. Still did not work. I then uninstalled jproject without removing remaining db table and it still DID NOT work. I removed any reference to jproject and then reinstalled the app. Re-populated the data and finally it worked again... Then I installed Community Builder. Jproject once again could NO LONGER be viewed on the frontend by clients. This happened at least 3 times before I finally decided to just throw the app away. After months of trying to get this running with little success, I did a little research and found Project Pier to be the best solution for my needs.
On a side note... I also purchased JAccounts. It's a good application, but not exactly worth $85. Support also isn't exactly the best. When I first purchased jaccounts and had an issue with the installation the response was "we are running xampp with no problem". Not exactly answer I was expecting. My recommendation is save your money.
