Resolved
Reported for: WPML Multilingual CMS 4.6.9
Resolved in: WPML Multilingual CMS 4.6.13
Overview of the issue
Under some scenarios, you may encounter a PHP warning like the following, particularly if you are using Google XML Sitemaps plugin alongside our system
Warning: preg_match(): Unknown modifier '-' in /wp-content/plugins/sitepress-multilingual-cms/inc/absolute-links/absolute-links.class.php on line 186
Workaround
Please, make sure of having a full backup of your site before proceeding.
- Open …/wp-content/plugins/sitepress-multilingual-cms/inc/absolute-links/absolute-links.class.php file.
- Look for line 186.
- Replace:
if ( preg_match( "!^$match!", $request_match, $matches ) || preg_match( "!^$match!", urldecode( $request_match ), $matches ) ) { - With:
if ( preg_match( "~^$match~", $request_match, $matches ) || preg_match( "~^$match~", urldecode( $request_match ), $matches ) ) {
Do we have to replace that line after every plugin update?
Until we don’t release a new version including a fix, this line may need to be replace.
We will keep this link updated.
When we can expect a permanent fix? it is showing the same error again and again after the updates. Please let me know

Hello there,
This is already in our devs roadmap. At the moment we don’t have an ETA but we will keep this page updated.
I tried this fix, then got a blank site and:
PHP Fatal error: Uncaught Error: Call to a member function get_requested_lang() on null in /home/wp-content/plugins/sitepress-multilingual-cms/sitepress.class.php:1131

I reverted and got the site back.
