We are having an issue where a trailing slash on the end of a URL turns into a double slash after the 'en-gb' section of our URL. Not sure why this is happening or how to stop it.
I am trying to: Stop this URL changing into one with a double slash when a trailing slash is added to the end of it: hidden link
Link to a page where the issue can be seen: hidden link (when put into the search bar it turns into a double slash after en-gb)
2) Also, as I can see from the website files, you are using a custom theme please check if the issue still happens when using the WP default theme, and only WPML plugins are active, all others are disabled.
