I cannot run the query in your phpMyAdmin for www.kalaa-sghira.com:

SELECT * FROM paypalshipping WHERE paystatus = 'Completed'

I can not see the last 3 pages of the records in the database.
it shows:
Warning: mysql_query(): Unable to save result set in C:\Domains\phpmysql.admin\wwwroot\libraries\mysql_wrappers.lib.php on line 108

Please send us the username, DB name and password for it to support@hostony.com.
I'll check it and try to fix this problem.
