Step 1: Identify the Problem

  • Where can the problem be?
    • Your browser
    • A plugin
    • Your theme
    • You may have been hacked
    • WordPress
    • Your server
  • Ask yourself – “What has changed?”
  • Is the problem due to your browser?
    • Make sure the problem exists in a variety of browsers
  • Is the problem due to a plugin?
    • Deactivate all plugins – if the problem goes away then it is a plugin problem
    • If the problem doesn’t go away:
    • Check to see if there are any caching plugins that add files
      • If there are, delete those files
      • If the problem goes away – then it was the caching plugin
      • If there aren’t, then the problem isn’t with a plugin
    • Leave all plugins deactivated
  • Is the problem due to the theme?
    • Switch to the default WordPress Theme – if the problem goes away then it is a problem with the theme
    • Check custom functions – do you have any custom code?
    • Check your theme settings – resave them
    • If the problem doesn’t go away leave the default theme
  • Is the problem due to hacking?
    • Test the site on Sucuri
    • If Sucuri finds malware – then fix it.
  • Is the problem due to WordPress?
    • if the problem persists with no plugins and the default WordPress theme and there is no evidence of hacking then the problem is with WordPress.
