I have my user
GRANT USAGE ON...
I didn't found a solution and nobody knew how to help me beyond to send me a manual with the definition of what
SUPER means in
MySQL so exploring all the files in my dedicated server and I found this path
C:\Program Files (x86)\Parallels\Plesk\Databases\MySQL\data\
I opened the
my.ini file, I located the variable
max_user_connections and I changed its value directly as I wanted, it solved my problem.
