Marco	Hi Bigul, How are you since WC Asia? I've downloaded and installed a fresh version of the plugin and the problem persists when using PHP 8.1, as you can see: hidden link

Bigul Supporter Languages: English (English ) Timezone: Europe/Vienna (GMT+01:00)	Hi Marco, Thank you for the updates. I am fine here. This requires further checking. So a couple of requests. 1) Please fill the private details fields after a full site backup{mandatory}. I would like to access the admin area of your site for further checking. Refer to the following links for more details about our private information sharing policies. https://wpml.org/purchase/support-policy/privacy-and-security-when-providing-debug-information-for-support/ hidden link 2) Please allow me to make a duplicator copy of your site using the Duplicator plugin(https://wordpress.org/plugins/duplicator/) for debugging the issue on my local server. -- Thanks!

Marco	This is a local development website. There's no way to give you access. Can't you replicate the issue by just having WordPress + WPML + PHP 8.1.9?

Bigul Supporter Languages: English (English ) Timezone: Europe/Vienna (GMT+01:00)	Hi Marco, Thank you for the updates. On my local server, I am currently using PHP 8.1 and WPML is working fine for me with WordPress 6.2. So will upgrade my PHP version to 8.2 and test it further. One help.

Marco	Hi Bigul, I did some debug and found out that this happens when, for reasons unknown to me, $php_host_domain is NULL on the filter_include_url function on class-wpml-include-url.php That happens when the $result input to that function is false. I need for you to set the private message again to send you the duplicator link.

Bigul Supporter Languages: English (English ) Timezone: Europe/Vienna (GMT+01:00)	Hi Marco, This bug is escalated to our developers and the fix for this will be included in the future version of WPML. Most probably in WPML 4.6.4. We will get back to you soon when we have an update on this release. Please wait. But we have a workaround for this bug. Please try the following steps after a full site backup and let us know your feedback. 1) Go to the wp-content\plugins\sitepress-multilingual-cms\classes\url-handling folder 2) Open the class-wpml-include-url.php file for edit 3) Scroll down to line 16 4) Make the following changes and save the file From public function filter_include_url( $result ) { $domains = wpml_get_setting_filter( array(), 'language_domains' ); $domains = preg_replace( '#^(http(?:s?))://#', '', array_map( 'untrailingslashit', $domains ) ); if ( (bool) $domains === true ) { $php_host_in_domain = wpml_parse_url( $result, PHP_URL_HOST ); $domains[] = wpml_parse_url( $this->get_unfiltered_home(), PHP_URL_HOST ); foreach ( $domains as $dom ) { if ( strpos( trailingslashit( $php_host_in_domain ), trailingslashit( $dom ) ) === 0 ) { $http_host_parts = explode( ':', $this->requested_host ); unset( $http_host_parts[1] ); $http_host_without_port = implode( $http_host_parts ); $result = str_replace( $php_host_in_domain, $http_host_without_port, $result ); break; } } } return $result; } To public function filter_include_url( $result ) { if ( $result ) { $domains = wpml_get_setting_filter( array(), 'language_domains' ); $domains = preg_replace( '#^(http(?:s?))://#', '', array_map( 'untrailingslashit', $domains ) ); if ( (bool) $domains === true ) { $php_host_in_domain = wpml_parse_url( $result, PHP_URL_HOST ); $domains[] = wpml_parse_url( $this->get_unfiltered_home(), PHP_URL_HOST ); foreach ( $domains as $dom ) { if ($php_host_in_domain) { if ( strpos( trailingslashit( $php_host_in_domain ), trailingslashit( $dom ) ) === 0 ) { $http_host_parts = explode( ':', $this->requested_host ); unset( $http_host_parts[1] ); $http_host_without_port = implode( $http_host_parts ); $result = str_replace( $php_host_in_domain, $http_host_without_port, $result ); break; } } } } } return $result; } -- Thanks!
