Migrated 1.6 to new server but can't find Class 'AppKernel'

[tivicrdotcom]

Hello fellow Geeks, so I am migrating an old but good 1.6 PS shop from one server to another, the new server/site is located at http://test.tivicr.com/tintagrafica/  and I am getting the following error:

Fatal error: Uncaught Error: Class 'AppKernel' not found in /home/at4gprieu0fh/public_html/tintagrafica/config/autoload.php:28

I have checked everything, files being where they are supposed to such as autload.php, app/AppKernel but can't find anything missing. I checked autload.php and that line reads:

define('_PS_VERSION_', AppKernel::VERSION);

I don't know where else to look for, to make matters worst, the original website (old server) now has the same error, so both sites are down, I guess going back and forth made matters worst.
 

Thanks in advance!

I have the same error on localhost (MAMP) after having installed 1.7.7.0-RC1. It was ok and then on terminal installed mpdf/mpdf via the directive

composer require mpdf/mpdf

Right now trying to figure out what's going on. It's probably something related to the composer (I guesss).

It didn't help me, however, dude.
