[Resolved] language switcher not working properly

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is experiencing an issue with the BetterDocs plugin on a multilingual site using WPML. When attempting to switch languages on a specific page, the redirection fails, stopping at an intermediate page instead of reaching the correct translated page. This issue is observed with incorrect URLs being generated for language switches.

Solution:
We recommend modifying the BetterDocs plugin code to ensure correct URL generation when switching languages. Here are the steps:
1. Open the file 

wp-content\plugins\betterdocs-pro\includes\class-multiple-kb.php

.
2. Locate the function 

doc_category_link

around line 695.
3. Replace the existing code with the following snippet:

public static function doc_category_link($termlink, $term, $taxonomy)<br />{<br />    if ($taxonomy != 'doc_category') return $termlink;<br /><br />    $kb_slug = self::kb_slug();<br /><br />    // WPML Workaround for compsupp-6478<br />    if (class_exists('SitePress')) {<br />        $kb_arr = get_term_meta($term->term_id, 'doc_category_knowledge_base', true);<br />        $kb_slug = $kb_arr[0];<br />    }<br /><br />    if (empty($kb_slug)) {<br />        $category = get_term_by('slug', $term->slug, $taxonomy, ARRAY_A);<br />        $kb_arr = get_term_meta($category['term_id'], 'doc_category_knowledge_base', true);<br /><br />        if (empty($kb_arr[0])) {<br />            $kb_slug = 'non-knowledgebase';<br />        } else {<br />            $kb_slug = $kb_arr[0];<br />        }<br />    }<br /><br />    return str_replace('%knowledge_base%', $kb_slug, $termlink);<br />}

This modification should correct the URL generation issue. If this solution does not resolve your problem, or if it seems outdated or irrelevant to your case, please visit our support forum to open a new ticket. We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.

Yes OK. just do not reconfigure themselves something. We need to do it ourselves according to your examples in order to control all changes (for example, links will become broken)

Hi,

1) I tried to login to check, but I got an error message. (Unknown email address. Check again or try your username.)

2) I won't change anything. I'll check the strings and the slug translation. However, if I couldn't spot the issue, I would need you to replicate the issue on the sandbox site for further debugging or if you have a staging site to debug the issue.

Regards,
Osama

Hi,

Thanks for the access details. I've checked your site and noticed two things that might cause the issue:

1) The knowledge base slug and the guide page slug are the same, which could cause the issue. (Kindly check this hidden link)

Would you please change the guide page slug to be (guides) in all languages?

2) The category slug is different in the better docs settings than the WPML settings. (Kindly check this hidden link)

Would you please change it in the better docs settings page to match the one in WPML settings?

After the above steps, please resave the permalinks, clear the cache, and check if the issue persists.

Regards,
Osama

betterdox answer:
Hello Alexey,

I have uploaded BetterDocs and BetterDocs PRO to the SandBox website. I hope the WPML team will help you to fix this.

I am sorry for this delay. Using all the BetterDocs default features, then the WPML will work smoothly. I noticed that you have made some pages in a custom way and also applied some custom conditions. Maybe it could be a reason for this issue.

Thank you

Congratulations, you now have access to the pro version.

there is also this answer wplms:

Thank you, the pages are loading in WordPress. This issue is not related to WPLMS as apart from the App section or Courses or Profiles rest of it is like a regular WP theme.

Everything in the issue is related to third party, third part post type, third party taxonomy, third party interface. I am sure the issue lies between BetterDocs + WPML.

However, I can see in the source the link generated seems correct but it kind of redirects to the page you have.

hidden link

redirects to

hidden link

Please check "Tool levels" is translated and synced in WPML. Since this is heirarchial taxonomy.

these are your recommendations hidden link
not yet fully verified.

Hi,

1) Thanks for your update. I'm not sure if WPLMS is related to this issue, but they said it's not related.

2) Kindly let me know the result when you test changing the Guide page's slug and the categories' slug.

Thanks,
Osama

Hi,

Thanks for your update. I'd need to consult our compatibility team regarding this issue, but we need to replicate the issue on a fresh installation in order to isolate it.

Could you please log in to this sandbox site, upload the latest version of BetterDocs, and activate the pro version? (hidden link)

After that, please create a knowledgebase, category, and post to replicate the issue. If the issue is replicable to the sandbox site, please let me know the steps to reproduce it, so I can escalate the issue.

Thanks for your cooperation

Regards,
Osama
