XF 2.2 Upgrade Tetstforum to XenForo 2.2.0 Beta 2

[Abraham54]

When uploading te upgrade files to the server my test forum showed the same error as it does to after the upgrade.
I run a health check and al files are complete,

This is the fault message my browser shows:

Warning: require(/home/u46315p74954/domains/piepcomprepair.nl/public_html/src/vendor/composer/../symfony/polyfill-intl-normalizer/bootstrap.php): failed to open stream: No such file or directory in /home/u46315p74954/domains/piepcomprepair.nl/public_html/src/vendor/composer/autoload_real.php on line 69

Very strange.
