I renamed the folder /dolphin/ to new folder /en/

I modified the 2 lines in the header.inc.php and everything  is ok except for the TEXT EDITOR MENU it is missing in every page with text editor. Please see attached file. I know I missed something.

have you cleared your cache?

Also have you cleared your tmp and cache_public of all files except .htaccess?

 Yes sir I did. I selected "All" via admin.

You may need to clear the cache manually. Use a FTP client and empty the /cache and /cache_public directories, except for the .htaccess files.

Huh, After seeing this I now have the same issue o.O 

ok I can confirm that to fix this you need to empty the /cache, /cache_public and /tmp directories, except for the .htaccess 

 Done for both /cache and /cache_public. But still the same, editor menu is now showing up. Sir, do you know what file or module that is responsible for that text editor menu? I think it has to do with the location of the file (if its a file).

Hmm, strange. Would you mind sending me your admin login so I can take a closer look?

 How are you clearing your Cache, Through Admin Panel or FTP?

Also did you to the same to /tmp?

 Thank you sir. Everything works fine now.

 I cleared the /tmp folder now and everything went ok now. Thank you sirs. God bless.
