How to Fix 404 Page or Page Not Found Error Messages

If you are getting a 404 page when you try to navigate to a certain page, or get a 'Page Not Found' error, this may be caused by a memory issue, an issue with the permalinks or a conflict with another plugin.

Follow these steps:

  • Check if you can solve this by changing the permalinks in "Settings > Permalinks" on your WordPress Dashboard. You should set it to "Plain" to troubleshoot.
  • If it does not work, check your memory limit in your system info in "Elementor > System Info" and ask your hosting company to raise it to, at least, 128MB by using this guide:
  • Switch the front-end editor loader method located in the settings of Elementor on your Dashboard via "Elementor" > "Settings" >"Advanced".
  • Ask also your hosting company to deactivate ModSecurity temporarily to rule out an issue with a rule set via this firewall. If it is the issue, checking the ModSecurity logs will help your hosting company to solve this.
  • Your host may need to enable zlib.output_compression module which can compress the data and may help with the loading of the editor when servers have limited resources.
  • Finally, you can also deactivate all your plugins besides Elementor and Elementor Pro, and switch to a default WordPress theme such as Twenty Nineteen to troubleshoot.
