mariaA-45	Tell us what you are trying to do? On my backend, the admin language switcher is broken. I cannot access any of my content anymore - pages/products. The front-end seems to be fine, just the backend is affected. What is the link to your site? develobaby.com What did you do? I have Danish as main language. English iand German were configured as translations, German was hidden, English was active. I deleted German from the WPML=>Languages settings and when asked, I deleted all German translations from the database. When I reloaded the Dashboard, the Language Switcher was broken and error messages started to come in... Which error messages do you see: At the top of the admin-backend, I see these error messages: Warning: Trying to access array offset on value of type null in /var/www/develobaby.com/public_html/wp-content/plugins/sitepress-multilingual-cms/menu/wpml-admin-lang-switcher.class.php on line 179 Warning: Trying to access array offset on value of type null in

mariaA-45	Okay, okay, everybody relax! This was apparently just a mild glitch. The problem was apparently that the Admin Language Switcher was set to German, which I had just deleted. Visiting a back-end URL with an existing language solved the whole issue, as the Language Switcher was able to recover when pointed at an existing language. phew I added this to my back end URL, because I knew that Danish 'da' exists: ?post_type=page&lang=da&admin_bar=1 Good weekend!

Christopher Amirian WPML Supporter since 07/2020 Languages: English (English ) Timezone: Asia/Yerevan (GMT+04:00)	Hi Maria, I am glad that you have managed to fix the issue. You also can change the language of the admin for each user by going to Users > Profile and change the language there. Thanks.

mariaA-45	Just for the record: I didn't think the back-end language switcher located in the top bar on every back-end was about switching the back-end interface language, but about showing contents (page, posts, products, etc) that the back-end shows for the chosen language. If that is correct, then I don't understand, what changing the user language in the user profile has to do with this ticket as this would affect, which language the whole back-end is presented in, but not which content to show. Best, Maria
