Good Day.

 I have been searching for other open source Blog Module for DNN 6, but I can't find one. I have tried installing DNN Blog module 4.0.0, to 4.1.1 and the same case I am experiencing.
The Add Blog Module Part function does not seem to work on DNN 6. Every time  I click add button I always receive this error message:

A critical error has occurred. Method not found: 'DotNetNuke.Security.Permissions.TabPermissionCollection DotNetNuke.Security.Permissions.TabPermissionController.GetTabPermissionsCollectionByTabID(Int32, Int32)'.

Some said this part of DNN core was overlooked and is being fixed in DNN 6.2, But I don't think upgrading to 6.2 is a good idea since the site is already live. I can't fully use such module if there is this error when I click add.

My current solution is that, I have tried to edit the code for mainview.ascx and hide the controls and button to add. The only problem in this solution is that, when the user click the delete button on settings of the module part. They cannot add it back. My idea is to remove the delete button in the setting, but I think it would only complicate the problem for the fact that the user might choose to delete some part of the module.

Guys, If someone can hear me  I really need help. If you have any idea on how I can resolve such issue, it would be a grace for me.
Thanks in advance.
