It is telling you, that a function is been called into use.
show_error_msg()
And it cannot find that function in the following files.
torrents-upload.php on line 278
torrents-edit.php on line 94
admincp.php on line 1667
admincp.php on line 774
You need to find where your functions are defined.
And see if the function is missing - or maybe commented out.
What version are you using ?
EDIT
I have this version
$site_config['ttversion'] = '2.00';
And in the folder backend - you will find functions.php.
You should have this function ( or something like it )
Code:
function show_error_msg($title, $message, $wrapper = "1") {
if ($wrapper=="1") {
stdhead($title);
//echo "<b>DEBUG: stdhead Wrapper ON/Kill php gen further</b>";//remove later
}
begin_frame("<font color=red>". htmlspecialchars($title) ."</font>");
print("<p><CENTER><B>" . stripslashes(sqlesc($message)) . "</B></CENTER></p>\n");
end_frame();
if ($wrapper=="1"){
stdfoot();
die();
}
}
