_chat_home_top_menu_sitem ??

I am not sure what this is , but it doesn't look like the right description of the flash chat 

how can i change it to chat??

it happened after upgrade naar 7.2 

Try to recompile module language file:

Admin panel > Modules > Add & Manage > select "Chat" > click "Recompile language(s)" button

if i compile it goes to the original one and discards all my changes in the file.

what is wrong??

whenever i compile the lang_en.php is the original one and not my modified one.

i put mine in /langs folder 

where does the old one coming from and why is it replacing mine??

Now it is working but when ever i compile the language it jumps back to the boonex default ( with about page and and yourcompany copyrights etc.)

what is it that i am doing wrong here??

i thought if you edit lang_en.php ( for english) then you are set , but obviously there is something wrong 

No, you do NOT edit the language files. You need to make changes in the database, by editing and adding keys via Admin Panel => Settings => Languagss Settings.

How do i edit the database then??

As said, from Languages Settings. Search for the key and edit it there.

no key edit possibility here 

Switch back to the Keys tab and enter the text or language key in the search box, then tick the checkbox to search. You'll see a list of matching keys with an Edit link, which you can use to view and edit the contents.

yup 

now it is working 

thanks for your time and patience :)
