Thanks @pacotole I have reactivated the plugin now. It’s working as before.
@jacob2019 you can login to your c panel and go to WP content file. Find Plugin folder there and then locate Polylang, rename Polylang or add old before name and save.
This should disable the plugin and then you should be able to login to your website. Once logged in you can update the plugin and rename to orginal before activating.
Hope this helps
