Some others recommended that they fixed by changing localhost with the IP. It is common to look this type of trouble when running WordPress on a local sever environments. For instance on MAMP, the DB_Host when modified to the IP may also appears to work.

Check your Web Host (MySQL Server)

Often you may note this Error setting up database connection when your website receives swarmed with a variety of traffic. Basically, your host server simply can not cope with the weight (specifically when you are on shared web hosting). Your website online gets in reality slow and for a few customers even output the error. So the excellent factor you must do is get on the phone or livechat with your hosting provider and ask them in case your MySQL server is responsive.

For those users who need to check if MySQL server is going for walks your self, you can do a few matters. Test other websites at the identical server to look if they may be having the difficulty. If they're additionally getting the equal blunders, then most surely there may be some thing wrong along with your MySQL server. If you do no longer have another site in this same website hosting account certainly visit your cPanel and try and get entry to phpMyAdmin and connect the database. If you could connect, then we need to confirm in case your database consumer has enough permission. Create a brand new file called testconnection.Personal home page and paste the subsequent code in it:


<?php

$link = mysql_connect('localhost', 'root', 'password');

if (!$link) {

die('Could not connect: ' . mysql_error());

}

echo 'Connected successfully';

mysql_close($link);

?>

If you can't connect to the database through going to phpMyAdmin, you then recognise it's miles some thing together with your server. It does no longer always way that your MySQL server is down. It may want to mean that your consumer does no longer have enough permission.

In our case, our MySQL server changed into running. All other web sites at the servers were running first-class besides for WPBeginner. When we attempted going to our phpMyAdmin, we ended up getting the error:

#1045 – Access denied for user ‘foo’@’%’ (the use of password: YES)

We were given on the phone with HostGator and their assist quickly located the trouble. Somehow our person’s permissions were reset. Not positive how that befell, but seemingly that was the cause. They went back in and repair the permissions and we were capable of get the web site again stay.

So if you get the get right of entry to denied error in both connecting on your phpMyAdmin or thru testconnection.Hypertext Preprocessor effects, then you ought to contact your host right away to get them to fix it.
