I set this up previously on a test site and everything went smoothly. However, now trying to replicate this on my live site it is failing to patch the last file, function_user.php. I tried to copy my function_user.php file from the working installation to the new one, however it still says "Error". When I click to patch the file, I get the "Patched file" message at the top, however still no workie. What can I do?
