FATAL ERROR after 1 click upgrade from 1.7.6.9 to 1.7.7.1

[Alex Ch]

I was upgrading to 1.7.7.1 from 1.7.6.9 and did a mysqldump before I press the button. The 1 click upgrade showed errors and ask me to "Roll Back",  I switched tap to another tab in Chrome and when I went back to the original upgrade tap, the button was gone and I went to another tab which was on prestashop admin panel and refresh, EVERYTHING LITERALLY GONE and ERROR 500.

The only thing I can get now is from the Error log in my nginx, which is:
PHP message: PHP Fatal error:  require(): Failed opening required '/web/www.addify3d.com/vendor/composer/platform_check.php' (include_path='.:/usr/local/php/lib/php') in /web/www.addify3d.com/vendor/composer/autoload_real.php on line 25" while reading response header from upstream, client: 162.158.111.188, server: www.addify3d.com, request: "GET /index.php?id_product=38&rewrite=makerbot-method&controller=product HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-cgi.sock:", host: "www.addify3d.com"

 

Please help... I have the backup and I dump in backwards it is still having the same error

Seems your shop is already live again. When restoring the DB you must also restore the files from previous version
