A 500 error means something is wrong with the code inside your website. This code is going to be found in the wp-content directory within your plugins or themes. These errors occur when something in the code of a plugin or your theme conflicts with that of another plugin, or is coded incorrectly. These errors can range from easy to challenging to resolve.
