Before your ticket is assigned to one of my colleagues, I'd like to guide you through some initial debugging steps to speed up the support process.
To begin, please note that there’s no best practice for changing the default language. Remember, changing the default language doesn’t change the original language of existing pages. For example, if you translated from English to Arabic, you’ll still edit from English to Arabic, not the other way around.
Also, all internal links may not update automatically, so you might need to adjust them manually.
Finally, consider the SEO impact: changing the default language will add /en/ to your English URLs, and remove the /ar/ from Arabic URL’s so you may need to set up redirects.
Here will be the steps to change the default language:
1. Take a backup of your site first for safety reasons.
2. Go to the WPML >> Languages page and change the default language by pressing the “Change default language” button as you can see in the attached screenshot.
3. Re-save Permalinks from the Settings >> Permalinks page by pressing the save changes button.
4. Clear all sorts of site/server/ CDN cache.
Please let us know if this resolves the issue or if you need further assistance.
Thank you
