Need Help - Warning: Invalid argument supplied for foreach

Hi dear people. I'm using Tiki cms groupware 8.3, however I get this error message:

"Warning: Invalid argument supplied for foreach() in /public_html/lib/init/tra.php on line 57"

This is on line 57: foreach (glob("lang/$lg/language_*.php") as $file) {

Does somebody know how to fix this? I have posed tra.php below

the first argument in foreach needs to be an array...

glob is probably failing for some reason, try print_r(glob("lang/$lg/language_*.php")); somewhere on a page in the same folder and see what is returned. it should show you the problem

Hi thanks for the kind reply.

Do I need to replace line 57 with that code line you suggest?

If that is correct, I get this message:

Parse error: syntax error, unexpected '}' in /public_html/lib/init/tra.php on line 83

What is the next step? Thanks again.

nope, i just wanted you to put that line i gave before somewhere on a page and see what it gave you, not replace line 57 in your function

Alright. Well I see nothing special. Still the same error is popping up. Do you have any more Solutions? :)

did you put that one line in a page, outside of the function and run it?

it should give you an array of files in the specified directory...

if it's not giving an array... that will be a problem .. because.. foreach needs an array for the first argument..

Please excuse me, for being a n00b in php programming.
I have put the line you suggested, at line 56, above line 57. Please explain to me where I need to put "that one line in a page, outside of the function and run it?" Thanks.
