Link to WordPress lost

[robertothai]

Hi,

I am using XAMPP for having WordPress on local host.

I had a problem with MySQL shutdown unexpectedly. I solved the problem by going to C:\xampp\mysql\data. I renamed the data folder, then I created a new data folder and copied all files from the backup folder to this new data folder. After that MySQL could be started again in XAMPP.

However, when I now try to access WordPress as before via http://localhost/name/wp-admin/, then I get an Error message Can’t select database.

Please could anyone help me to re-establish the connection?
Thanks a lot in advance and best regards,

Robert
