Yes, I followed those steps before I used the One-click installation. Created the database, modified the web config file. And had the same problem.
So I deleted the wordpress folder, deleted the databases and tried one click installation and had the same issue.
Could it be because I didn’t link my Domain’s DNS to my hosting?
I just added gandi’s DNS to my plesk DNS settings, but I heard it takes up to 24 hours to fully update.
Any other suggestions?
