Forum User Cannot View Private Messages after upgrade 4.0 RC4

[AL Master]

Hello,

 

The Forum members just cannot , view the private message page,, they got this error

 

PHP Fatal error:  Call to a member function author() on a non-object in C:\Inetpub\vhosts\*********\httpdocs\system\Theme\Theme.php(624) : eval()'d code on line 628

 

For admins I've tried Empty folders action , and its works but on members,, that doesn't work...

 

is There way to empty all private messages on forums?

 

Regards
