If you are redirected to a Page not found or white screen when you submit a new property or when you edit a property, you need to check the following
-
The User dashboard page for editing is created and Published
2. Review any custom changes applied in the Theme code.
You can add a clean theme to confirm that custom changes are the fault.
A clean theme must be tested with the original code.
We usually add such themes by creating a backup of you current theme via FTP and adding a new one from wp-admin.
Or we can add a renamed version of our theme so your current theme doesn’t need to be renamed from FTP.
3. Disable all 3rd party plugins to see if this issue still exists (in case you didn’t make any theme customization, this is always step 1).
4. Enable debug and check the error log.
Go to wp-config.php and enable debug to true-check errors. Help: http://codex.wordpress.org/WP_DEBUG
If you see these errors:
PHP Fatal error: preg_replace_callback(): Cannot use output buffering in output buffering display handlers in public_html/wp-content/plugins/elementor/modules/image-loading-optimization/module.php on line 123
PHP Fatal error: wpestate_get_calendar_price(): Cannot use output buffering in output buffering display handlers in public_html/wp-content/themes/wprentals/templates/submit_templates/property_price.php on line 100
The cause is related to PHP settings. More exactly something related to output buffering which is too small this causes some plugins like Elementor and WpRentals core to not work correctly. You need to set the output_buffering to a bigger value.
