Thanks.
Could you, please, post here how you have configured the items?
For first redirect:
jocuri?fid=2 => /jocuri
This should word:
From URL: jocuri?fid=2$
To URL: http://{siteurl}/jocuri
For second problem:
/index.php => /
It should be configured as follow:
From URL: /index.php$
To URL: http://{siteurl}/
Remember that ReDJ uses regular expressions to match current URI with configured item. So, if you configure a simple "index.php" it matches also for "/component/puarcade/index.php?gid=125". This is the reason why I use "/index.php$" were the dollar at the end means "Match the end of a string". For more information on the power of regexp:
