• PHP is a programming language WordPress. The WordPress files have been written in PHP
• MySQL is a database technology. WordPress uses a MySQL database to store all of website’s content. This includes posts, pages, title of the site, the color settings, etc. MySQL is where every smallest piece of information about the website is kept.

This is where the error occurs when, WordPress cannot access the information in the database via PHP commands. When that happens, WordPress does’nt know what to do next, so it say “Error establishing a database connection”.

There can be reasons why the error occurs. Some of the common reasons are:

1. Incorrect Login Credentials

WordPress needs a specific login and password to access the database. If those change for any reason, then WordPress will no longer be able to bring anything from the database.

2. Corrupted WordPress Files

The core WordPress files can get corrupted as of a failed update among others. This includes things like failed updates of the plugins, themes, and the main WordPress software updates.

3. Corrupted Database

This might result of a rogue plugin messing up the database internally, a hacker’s attack, a theme failing, etc.

4. The Database server is down

In some cases, the web server run on a different machine than the database and that separate database server can be down for whatever reason.

5. Too much traffic

The database might be unresponsive due to high spike in traffic.

How To Fix “error establishing connection”

Step 1: Get in touch with your Web Host Provider

If the site was working a minute ago or a day ago and now there is a fault that fault can be on web host’s end. All quality hosts offer some form of fast-reacting support, usually through live chat. Most importantly, they will let you know if your database is alright or not or whether any suspicious activity on the server.

Step 2: Check if your Plugin or Theme files haven’t been corrupted

1. Connect to your host via FTP, or can be done with a free tool called FileZilla.
2. Go into “wp-content” and rename the “plugins” folder to something else.
3. Go back to your site and see if the error is still there.

Either delete it or go online to see if the solution has been documented.

• If the error is still there even after renaming the “plugins” folder, go through the exact same process with the “themes” folder.
• If that doesn’t help, rename both the folders back to “plugins” and “themes”. The error is accused by something else

Step 3: Check if your Database hasn’t been corrupted

1. Go to your WordPress dashboard.

If you see the same error “error establishing a database connection”, skip that step.

2. If you see something else, pay attention to what WordPress is suggesting you to do. In the recent version, WordPress has expanded its problem-solving solutions.

One of the possibilities is that you will see a message starting with “one or more database tables are unavailable”. This means that is needs to repair the database.

The repairing is quite simple. First, connect to your site via FTP once again. Go to WordPress root and download the “wp-config.php” file to your desktop.

Now upload the file back to your site (via FTP) overwriting the old version. Once the automatic repair finishes, go back to your site and see if the error is still there.

Step 4: Check Your Database Connection Credentials

define( ‘DB_NAME’ ,  ‘some_db’ );
define( ‘DB_USER’ , ‘some_username’ );
define( ‘DB_PASWORD’ , ‘some_pass’ );
define(‘DB_HOST’ , ‘localhost’ );

Take those four lines mentioned above from the “wp-config.php” file, copy them to the clipboard, contact your web host support again, paste those lines in the chat window and ask if the details are correct for you to be able to connect to your database.

The representative will check everything and come back with some feedback. Most of the time they provide with the correct details in case anything has been changed.

Now take the credentials and put them in your “wp-config.php” file where the old ones used to be. Finally upload the file via FTP. At this stage you can go back to your site and see if the error has been fixed or not.

Step 5: Restore the Default WordPress Files

The easiest way to restore the defaulted files is to just download a clean version of WordPress from wordpress.org and copy it over the one you have right now.

Download the newest package to your desktop. Unpack. Browse through the unpacked archive and delete the “wp-content” folder.

Next, connect to your site via FTP, go to the main WordPress root, upload your new WordPress files. Overwrite all the previous files. When the upload is done, go back to your site.

Almost all of our servers run on PHP as CGI binary. One of the side effects of PHP as CGI binary is that internal service error problem can occurs at any time if the permissions of files and directories are set incorrectly. Internal server errors can also occurs if there are certain PHP directives defined in an htaccess file. 500 internal service error is a common problem in HTTP file transferring process. 500 internal service problem may happen because of some faults in.htaccess files, PHP memory limits or a slew in some other random issues. It is a very common and annoying problem that occurs very frequently while working with files. Most people become very confuse to deal with it.

What is a PHP file?

Full form of PHP is Hypertext preprocessor(or simply PHP). It is a server-side scripting processor or language designed for specially Web development. PHP originally stood for personal home page. But now it now stands for the recursive initialism PHP: Hypertext preprocessor. PHP code may be embedded into HTML code and can be used for various web pages and web frameworks. The standard PHP interpreter is a free software released under the PHP license. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge. It is a very common web language and is used in wide range allover the world. There are two primary ways for adding support for PHP to a web server- as a native web server module or as a CGI executable. PHP has a direct module interface called SAPI(server application programming interface) for different web servers. Numerous configuration options are supported, affecting both core PHP features and extensions.

What is 500 internal service error?

The 500 internal service error is a very common HTTP(hyper text transfer protocol) code which means something has gone wrong on the server’s page or website server but the server is not specific of the exact problem. In other words, it means that the server can not process your request for some unknown reason. The problem is not with your gazettes like smartphones, computers, desktops, or laptops, but its entirely a system related or website problem. Sometimes there can also have some massage to reload your page or to try again later or back to previous page or unable to open the page due to some unknown reason etc.

How to deal with 500 internal service error problem?

As we have discussed earlier that 500 internal service error problem is a very common system oriented problem, there are some possible ways to deal with it.

Reload the web page. You can do that by pressing the refresh or reload button, pressing F5 or Ctrl+R or trying the URL again from the address bar. As this error is generally a server-send error, reloading the same page after sometime can be helpful in solving the problem.

We have discussed earlier that it is a very annoying and frustrating error because it does not have any straight forward solution. At the same time it takes so much time and sometimes really makes hindrance while doing some important works. We need to do a lot of troubleshoot to deal with it. It can push a WordPress beginner in a panic mode.

How To Fix 500 Internal Server Error in Php

1. Checking  .htaccess files can also be helpful. Sometimes renaming the same files with some extensions like .htaccess_bt or anything can help in dealing with this problem. As ‘htaccess‘ is a hidden file, we need to select the hidden file option in our configuration setting to rename it.

2. Checking the PHP version can also be a solution as the last server supported php version is 5.3

3. Checking PHP memory limit can also be a troubleshoot. Plugging, scripts and themes often use huge memory which can cause internal server problem. In this case all you need to do is to add following line of code memory_limit=256M in your code. Php

This error can also be a result of WordPress core file corruption. At this time all you need to do is to re-upload a fresh version of wp-admin or other official files.

Conclusions 

500 internal error problem php is a very common problem. So follow the solving suggestions that are discussed in this article. Hope it will be helpful in your future usage.
