Problem:
If you're experiencing server errors on your site that make it very slow and often go away when you reload the page, we have identified a potential solution.
Solution:
First, you might be facing an issue that requires adding specific code to your theme's functions file to correct rewrite rules:
1. Using FTP, navigate to `/wp-content/themes/your-theme`.
2. Open the `functions.php` file for editing.
3. Add the following code and then save the changes:
add_filter('mod_rewrite_rules', 'fix_rewritebase');
function fix_rewritebase($rules){
$home_root = parse_url(home_url());
if ( isset( $home_root['path'] ) ) {
$home_root = trailingslashit($home_root['path']);
} else {
$home_root = '/';
}
$wpml_root = parse_url(get_option('home'));
if ( isset( $wpml_root['path'] ) ) {
$wpml_root = trailingslashit($wpml_root['path']);
} else {
$wpml_root = '/';
}
$rules = str_replace("RewriteBase $home_root", "RewriteBase $wpml_root", $rules);
$rules = str_replace("RewriteRule . $home_root", "RewriteRule . $wpml_root", $rules);
return $rules;
}For more details, please refer to the documentation: https://wpml.org/faq/why-is-htaccess-getting-overwritten-with-the-language-folder-on-my-wpml-website/.
Additionally, to identify the exact cause of the errors, enable debugging in your site.
To enable it, open your wp-config.php file and look for define('WP_DEBUG', false);. Change it to:
define('WP_DEBUG', true);
To enable the error logging to a file on the server, you need to add yet one more similar line:
define( 'WP_DEBUG_LOG', true );
The errors will be saved to a debug.log file inside the /wp-content/directory.
