Reproduce

• Login ACP -> Configuration -> Languages
  
• English -> Options -> Edit Language Variables
  
• Admin CP -> users_users.lang.php -> Edit.
  

See that instead of going to edit page, you are led to index page of forum.


Same thing happens with all languages.

it seems fine check on 2 boards
my live forum and fresh installed test board

I checked and there's no difference between my user_users file and 1.8.21 fresh user_users file, any idea what might be causing this?

Cannot reproduce, please check your URL setting in ACP.

It only happens with this lang file, others work normally.

It could be a cache problem.

Okay so yesterday I checked:

• If there's any missing ";" that makes me unable to open file in ACP, found none.
  
• If there's any permission issues, there's none.
  
• I checked if any content of the file might be causing this, even if there's only 1 lang line "Users" the file still not opening in ACP.
  

Again, I can open every other lang file in ACP, I can't open this one.

This is obviously not a bug, since it can't be replicated. Have you tried replacing the file from a clean install package? Completing clearing your browser cache? Its not impossible that you might have something in your htaccess causing a redirect.

Further to the above, I would also suggest to deactivate all plugins if any installed.

I cannot reproduce, it seems as a cache/plugin issue. Can be closed.
