Glad I could help. Please mark the topic as resolved if the problem is now solved ??

Zaborowski : Can you tell us when did the error occured??

Do you mean the images in the new page or post you created is not clear??

If yes then may be the problem came when you uploaded the images. When you upload an images, after upload completes wp asks you if you want to insert into post or use as featured image or some other options if available. In the same page, there is also an option to determine some sizes of the image, most probably you when you uploaded the image, a small size of the image was selected.

Please Check it. ??

You cannot alter your database tables from Filezilla.

First login to your control panel and look for phpmyadmin.

When you go inside phpmyadmin, it will sometimes ask for your mysql username and password.

After the authentications, you can access your database.

Then select the database and use the inbuilt search function to search for yoursite.com/blog and then when you find them, edit them to yoursite.com

search all your database tables and find yoursite.com/blog and rename it to yoursite.com

Try putting localhost where it asks for host.

First make sure that you have properly set the database (old one) and make sure the link is right. eg:https://yoursite.com

Secondly upload your new wordpress to your server but don’t run it from browser yet. There is a file named wp_config_sample.php, rename it to wp_config.php and open it. There edit 3 things your database name, database username and password

this is where to edit.

// ** MySQL settings – You can get this info from your web host ** //
/** The name of the database for WordPress */
define(‘DB_NAME’, ‘database_name_here’);

/** MySQL database username */
define(‘DB_USER’, ‘username_here’);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘password_here’);

If the url in your database matches the url to your wordpress site. The should properly work with all your old stuffs.
