What Cause Fatal Error

WordPress fatal error can be caused numbers of factors such as:

  1. Bad Coding – A poorly coded plugin will cause problems regardless of what theme and plugins you are using.
  2. Conflict with WordPress – Plugin code can be incompatible with the code used in the WordPress core files. Due to this, most plugin developers update their plugins after a new version of WordPress has been released to ensure that their plugin is still compatible. Unfortunately, many plugin developers do not do this, which is why you need to be extra careful when installing older plugins.
  3. Conflict with Another Plugin – Plugins do not always play nice together, particularly when the plugins offer similar functionality.
  4. Conflict with Your Theme – Many theme functions are placed in the theme’s functions.php file. The principle of extending a theme’s functionality using functions is the same as adding functionality through a plugin. As such, problems can occur if it is coded badly or if it conflicts with another plugin.
