How to Fix Common Server Problems

Using WP_DEBUG to Make Troubleshooting Easier

WordPress is equipped with WP_DEBUG giving you a detailed description of what caused the error. WP_DEBUG is turned off by default and must be enabled by changing a variable inside of your wp-config.php file. This is how you can enable WP_DEBUG.

1. Log in to your Control Panel.
2. Go to File Manager.
3. Locate the wp-config.php file for your WordPress website.
4. Edit your wp-config.php file.
5. To enable WP_Debug, add the following code to the end of the file:

• /**
  * WordPress Debugging
  *
  * Set to “true” to enable wp_debug. Set to “false” to disable.
  * Do not include quotes when setting to “true” or “false”.
  */
  define( ‘WP_DEBUG’, true );

To disable WP_Debug, change the last line to:

• define( ‘WP_DEBUG’, false )

Click Save.

Important: WP_DEBUG requires additional resources when turned on and could slow down your site. We recommend that you only turn WP_DEBUG on when you are developing or troubleshooting your website. You can Learn more about debugging in WordPress

PHP Memory Limit Exceeded

PHP Memory Limit Exceeded is also one of the most common server problems. Your website, theme, and plugins require PHP memory in order to run properly. If your combined resources consuming too much memory, your website may give you an error. Fortunately, there is a way to increase the memory limits that your WordPress website allows itself to use. You can increase the PHP memory limits by editing a wp-config.php file or php.ini file or you can simply ask your hosting provider to increase the memory limits of your PHP.

MySQL Query Limit Exceeded

Similar to PHP Memory Limit Exceeded, MySQL Query Limit Exceeded is also a very common server problem. A “query” refers to a single “question” being asked to the database to retrieve information such as retrieving the contents of a blog post or confirming login credentials. Because every MySQL Query consumes server processing power so many hosts limit the number of queries that any single user can perform within an hour. This limitation protects other users on the shared hosting from suffering negative effects caused by a single user by utilizing too much processing power. You can talk to your hosting provider about the limits of your MySQL queries. you can ask them to ask the limits or simply upgrade your plan to the VPS(Virtual Private Server). This will fix the problem.
