Hi there,
I’m so sorry that I haven’t got back to you before now! And that you’ve had to wait this long! For some reason, WordPress didn’t send me any emails to let me know that there were support questions!
You’ve probably solved this by now, but the file it is looking for is Autoloader.php which is part of the Twig library. This file is basically what sets Twig off running
I hope this helps!
Mike
Tried installing again, got the most recent version, activated it, and got the same error message. Please include the auto uploading file in your next update.
The file isn’t part of this plugin, it’s part of Twig which is a 3rd party library. You need to download Twig from here: http://twig.sensiolabs.org/.
In the download file you’ll get, you’ll need to drill down a couple of levels until you find a folder called Twig which contains Autoloader.php. This is the folder you need to copy into wp-content. Once this is there, the message will disappear and you’ll be ready to use Twig!
Mike
