Hello Theo,
May i know where you put the sql dump file in your FTP?
Regarding with your new site is using this path file location right -> brandweerdeurne.nl/public_html/1941 ?
If yes, you can put your sql dump file in your location file -> brandweerdeurne.nl/public_html/1941/tmp
So i can easily to get your sql dump file in your FTP.
Also, i have tried to access in your Joomla backend (
http://www.brandweerdeurne.nl/1941/administrator/index.php ), but i getting this :
Warning
De combinatie van gebruikersnaam en wachtwoord is niet correct of u heeft nog geen account.
You have to provide us with your phpmyadmin access for your new site, so i can import the sql dump file in your new database.
Please advise.
