Microblog module interferes the permissions of other content types

After installing the microblog module, authorized users lost their access to create content. "access denied"
Changing the rights of other content types (under users tab) didnt have any effect at all. So i guess microblog was overriding those permissions (cause microblog permissions were really limited)
So after disabling the microblog module, adding content for all users is working fine again.
