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, 256MB by using this guide: https://wordpress.org/support/article/editing-wp-config-php/#increasing-memory-allocated-to-php
- 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.
