Conflict with WPML

Hi @dimmex,

1 OK, just to make sure I understand the issue, if you have either NextGEN Gallery or WPML on their own, your permalinks work fine, only the defined URL works, as soon as you have BOTH plugins (hopefully you tried this with no other plugins active) the issue triggers. Right?

2 You can try using canonical, Google Search Console exclude crawling by URL parameters and/or maybe sitemaps.

Please keep me posted.

Yes, you understand correctly. The problem arises ONLY IF these plugins are operating together. It’s possible that there is a disabling of the redirect to canonical permalinks. This is because if either Nextgen or WPML is deactivated, the redirect functions correctly.

Hi @dimmex,

I am sorry, but it doesn’t look like I wasn’t able to replicate the problem.

Could you please let us know what permalink setting do you have in “Settings>>Permalinks” and also what do you use for “WPML>>Languages>>Language URL format”?

Hi!

The WPML url settings are using Languages in different catalogs.

I contacted WPML developers with the same problem. They saw this problem too.

The problem is easily reproducible on pure WordPress with any design template. Just install WPML plugin and Nextgen Gallery, create a page of format “page” and try to open it by canonical url and url of format ?page_id. Under normal operation, there should be a redirect to the canonical url, but it doesn’t work.

WPML tech support offered the following solution:

Our team investigated and found the following workaround:

// WPML fix. if ( in_array( ‘SitePress’, get_declared_classes(), true ) ) { Router::$use_canonical_redirect = true; Router::$use_old_slugs = false; \add_action( ‘template_redirect’, [ $this, ‘fix_wpml_canonical_redirect’ ], 1 ); }

which you can add to app/public/wp-content/plugins/nextgen-gallery/src/Util/ThirdPartyCompatibility.php file after the following code (line #108):

// Like WPML, BuddyPress is incompatible with our routing hacks. if ( function_exists( ‘buddypress’ ) ) { Router::$use_canonical_redirect = false; Router::$use_old_slugs = false; }

What do you think? Will it work?

Hi @dimmex,

I will ask the developers to take a look and also ping Mihai.

Thanks

Hi @dimmex,

Just as an update here, our developers are reviewing the fix provided and the possibility of including it in one of the future updates.

Thank once again for bringing it up to our attention and for sharing the fix suggestion, we do appreciate it.

Hi @dimmex,

I am happy to inform you that our developers have implemented the suggested WPML fix in NextGen Gallery 3.58 version. ?

Please feel free to update to the latest version of NextGen Gallery, then let me know if it works.

Thanks!

Yes! After the update, everything works correctly! Thank you! Problem resolved.
