Well we just told him the phase one of his problems,he might still have doom set ahead of him
@damseremie ,
well if that works, lets hope it does, you "might" have to either create a replica user you have locally with the one online and set a global privilege to the user.
from my understanding, you know how to use PhpMyAdmin not Myphpadmin (since its yours, it sure wont work

) so like prodgalson said do the export thingy
Since you used dreamweaver, yyou'dalso have to edit a .php file in your siteroot/Connections/ folder ,
you sshouldsee somfin similar to this
1 <?php
2 # FileName="Connection_php_mysql.htm"
3 # Type="MYSQL"
4 # HTTP="true"
5 $hostname_examguide = "localhost";
6 $database_examguide = "examguide";
7 $username_examguide = "timmy";
8 $password_examguide = "abstract";
9 $examguide = mysql_pconnect($hostname_examguide, $username_examguide, $password_examguide) or trigger_error(mysql_error(),E_USER_ERROR);
?>
you might have to edit line 5 (but not always, most likely that remains the same value and if u used 127.0.0.1 locally, change it to localhost online)
but certainly your line 6,7 and 8 most be well monitored else yuld be setting for doom, i just pray your client is the gentle type else na yawa for you,
anyways like i said lets know the kind of admin panel your host support, then i could give a precise help.
