Describe the issue or problem
I have upgraded OJS from version 3.2.1.5 to 3.3.0.20 with a success message, but when I try to access the website, I get an HTTP 500 error. I checked the error log and found the following message:

What application are you using?
OJS 3.2.1-5 to 3.3.0-20
Additional information
I have already verified that the database name and file locations are correct. I also tried disabling plugins, even though there were no indications of plugin-related errors.
I would appreciate any help or suggestions on how to resolve this issue.
