 * I reset my password in MySQL Database. After the reset, I couldn’t log in to 
   my blog anymore. It says, Error establishing database connection.” By the way,
   I have a special login url set in the AIOWPS plugin. I couldn’t be wrong with
   my special login slug because I have bookmarked it, plus I also have a copy of
   it in my password manager app. I tried deleting browser cache and cookies, also
   tried another browser, but still failed to login.
 * Please help!

 * Did you update your wp-config.php file with the new password too?

 * You can edit your wp-config.php via your hosts control panel.
    Locate file manager
   and click it select the desired domain name (if you have more than one hosted)
 * if you see the folders bellow then you are in the right folder:
 * wp-content
    wp-includes wp-admin
 * if not check if you see a public_html folder and double click it
 * locate the wp-config.php and right click on it,click edit and wait till the file
   open
 * find
    define(‘DB_PASSWORD’, ‘YOUR OLD PASSWORD WILL BE HERE’); and alter it to
   be define(‘DB_PASSWORD’, ‘WRITE YOUR NEW PASSWORD’); save the file and try to
   open your website.
 * if you are unsure or you cant follow the directions contact your host and ask
   them to do it for you.

 * I have set up a new Sub Domain and am unable to connect to the database – I have
   checked and checked that all the user, host and password etc details are correct–
   the only thing different is that my new database is MySql 5.5 – is this causing
   the issue – all MysQL 5.1 sites are working fine
