Message System Error

[WPCom]

Hey, 

I recently upgraded to the newest version of IPB 4. On update, the inbox has had some issues. I am getting this error when I try and view the inbox:

[[Template core/front/messaging/messageListRows is throwing an error. This theme may be out of date. Run the support tool in the AdminCP to restore the default theme.]]

Looking into the system logs, I have found this:

Missing argument 4 for IPS\Theme\class_core_front_messaging::messageListRows()

#0 /home/dinc/public_html/forum/system/Theme/Theme.php(718) : eval()'d code(836): IPS\IPS::errorHandler(2, 'Missing argumen...', '/home/dinc/publ...', 836, Array)

I have tried looking into all the files listed, and I cant seem to find the solution. The problem occurs on every theme I try except for the default theme.

Thanks for the help!

Same problem here - with the unchanged default template.
