Right after Pligg announced the new 1.1.3 version, I was excited to download it and try it. However, I faced a some kind of disappointment. The voting system was not working; at the beginning, I thought a file must have been corrupted or there is something wrong with my database. But that was not the real Issue. So what is the solution?
The problem is mainly from the database and while the installation, some fields were not created. So what you should do to fix this is to upload the /install/ directory again and run yourwebsite.com/install/upgrade.php It will ask you whether you want to upgrade the database and the language file; once the upgrade is successful, the function will work perfectly.
Pligg team has announced that they are working to solve the issue as soon as possible. I will update this post when the problem is fixed.
