If the form is not displaying properly and links on the page result in “Page Not Found” errors, you may be experiencing problems with friendly URLs. So, you need to check if Apache ‘mod_rewrite’ is enabled.
Also, you need to check in your Apache config file, if the .htaccess files are enabled:
<Directory /your/path> AllowOverride All </Directory>
If the problem persists, you can disable pretty urls:
1. Open the ‘@app/config/web.php‘ file
2. Replace the line:
'enablePrettyUrl' => true,`
By:
'enablePrettyUrl' => false,`
