How to prevent Syntax Error in WordPress


Cause:

Syntax errors are usually caused when users try to add incorrect code snippets in WordPress where the syntax formation is wrong.

When faced with a syntax error, users will see an error message with the title “Parse error- Syntax Error”. The remaining part of the error message will indicate the location, line number, and error found in the code script.

How to prevent it?

Syntax error means that the formation of your code snippet is incorrect, meaning that you might have forgotten to include necessary commas, brackets, etc.

To prevent the syntax error from happening again, use the Code Snippets plugin for WordPress.

What the Code Snippets WordPress plugin does is that it allows you to manage the custom code snippets that you use on your WordPress site by creating a custom field with a title for the snippet.

In the worst case, if the snippet has some syntax error, the plugin automatically detects it and disables the plugin thus preventing your site from displaying a syntax error message.
