Hej.
Som @boldt skriver så hans anbefaling absolut den bedste løsning, jeg bruger alid den løsnig selv
Her er hvordan du gør:
Using phpMyAdmin, select the database of the site that has the lost password. Then locate the line wp_users and click browse (ist icon) You will see a list of usernames with passwords (encoded) On the line with the user name and password you lost, click the pencil(ist icon)
You will then get a screen with the data for this user including the encoded password. Delete the encoded password and enter an easily remembered password in ASCII format- example TEST, then on the pulldown list to the left of the password, select MD5. Then go to the bottom of the form and click GO.
Go back to the site and use the ID and password you just entered. After you get on the site, change the password to something secure.
