If you open the patch file, it should show something like the following:
--- some/path/to/some/file.ext
+++ some/path/to/some/file.ext
- if($var)
- {
- echo $val;
- }
+ if($var && ($var & $var2))
+ {
+ if($val != '')
+ echo $val;
+
+ echo $var2
+ }
Essentially, it tells you that you need to (-) remove or (+) add lines to the specified file.
Hope that helps. If that's not it, try opening the file in a text editor, and viewing its contents. If you don't understand it, paste the code here.
