And no Wordpress was not installed before… he always aborts the installation between 10 and 20 percent
You can even install it manually instead of installing it using Softaculous. Click on me to go to the detailed instructions. To the databases part, go to your cPanel, go to MySQL Databases, create a new database with the name epiz_xxxxxxxx_wordpress (where xxxxxxxx will be the random numbers of your hosting account username). After that note the DB name, go to your Client Area and on your hosting account there will be username and the password (the password is hidden, use the Show/Hide button to show it). Copy them and paste them in a notepad, upload all the files from the wordpress folder in your htdocs folder using FileZilla (you need to configure it with the hostname ftpupload.net, username and password of your hosting account and plain FTP), go to your domain and follow the step 5 from “Setup configuration file” of the detailed instructions. Also note the SQL host, which will be sql123.epizy.com, where 123 is the random number assigned to your database server! So, note the database name and the SQL host and copy them and paste them into your notepad where are the username and password of your hosting account. Then, put the database name you pasted into the notepad, the username and password of your hosting account and the SQL host of your account. Then submit and follow the detailed instructions from “Finishing installation”, not using “admin” as a user ID.
