Hello,
To reproduce the issue, try creating the following WordPress websites:
my.wordpress.website.com.aa
my.wordpress.website.com.bb
My analysis is the system fails because it tries to create database name based on first 12 characters in domain, for example:
sql_my_wordpress
sql_my_wordpress (fails)
Can you please add the ability to decide DB name myself on the wizard?
Kindly investigate the issue and thank you for your efforts.
