Blank page was showed when the website was upgrated


The blank page was showed When I upgrade the site from 3.0.2 to 3.1. I checked the error log.

At the end of log, it showed

[20-Dec-2017 09:40:20 Asia/Shanghai] PHP Fatal error: Call to a member function getId() on a non-object in /home/wwwroot/lanmp5.3/domain/ on line 2480

How can I fix this

Thanks in advance

Hi @littlemeizhi

When you run upgrade script did you receive a successful message at end?
I could suggest you re-ran upgrade with a restore database and files from backup to double check that this process goes well.
