Error during upgradation


Recently i upgraded my suitecrm site from 7.1.x to 7.2.2

During upgradation, error occured ( see attached error when upgrading.png )

After error occured, I again went to upgradation wizard to check what is the status ( see attached upgrade wizard after error.png )

Now there are issues in my site for example one issue i came across is menu css is messed up ( instead black background there is white background See attached css issues in site.png )

Thanx in advance for any guidance
