"Cannot instantiate class. Class "IssueDAO" is not declared in "classes.issue.IssueDAO"

Hello,
I moved my ojs 2.4.5 to another server. However when I change language from English to Turkish, I’m facing an error below:

"Cannot instantiate class. Class “IssueDAO” is not declared in “classes.issue.IssueDAO”

Do you have any idea about the problem?
Best wishes…

Hi @Tacettin_Inandi,

You’re probably running into this PHP bug or something related. What version of PHP are you using?
