To replace the phrases to Arabic do the following:
1). Open the 'ban_from_thread' product and at the bottom you will see all the phrases.
Code:
<phrase name="xxx"><![CDATA[yyy]]></phrase>
2). For each phrase replace the 'yyy' text with your own. Only the 'yyy' part, not the 'xxx'.
3). Re-upload the product via the admin cp product page and be sure to select '
Allow Overwrite'.
4). Done.
P.S.
Is your site Lebanese? If so, I used to be your neighbour
