Cant change welcome message


I have been trying to change the the Welcome message on our new server.

There is word organize that we would like to change to organise. I have searched through all the files on the system and changed every instance of the word organize to organise, yet the system still shows the message with the word organize. Could someone please help with how to correct this?

Thank you very much

Best regards

Got this one resovled by editing values in files

and had to clear cache in browser in the end.

I cant tell if this is the right way to do this, but its what worked for me.

If anybody has a comment, it would be appreciated.

Thank you
