Export & Import Database

Thank you again for the reply,

I did import the data and everything is fine but i'm facing a weird problem, when I change anything in the global parameters such as ldap smtp...etc and save it it says parameters saved, but when I return to the page all the input data will be gone,
so I went to the httpd and checked the parameters.php and compare it with the old setup.

please attachments. thank you!

*when I change any thing in parameters.php it reflects on global parameters.

again thank you so much for your valuable time and help
