when I click in the configuration at joomblog to save , I get only a blank page appears . it changes but nothing .

is ist normal that super user has no rights?

I have exact same problem... no solution yet?
Actually, in my config, the Super User has rights, but still unable to change anything..
Blank page with this url: index.php?option=com_joomblog&layout=edit&id=769

The first step in this article helped:

Now I get an error message so can probably fix the problem...

Strict Standards: Declaration of JoomBlogControllerSettings::cancel() should be compatible with JControllerForm::cancel($key = NULL) in administrator/components/com_joomblog/controllers/settings.php on line 15

Fatal error: Declaration of JoomBlogTableSettings::store() must be compatible with JTableInterface::store($updateNulls = false) in /administrator/components/com_joomblog/tables/settings.php on line 100

I found these files and edited them, putting the code in the brackets like the error message says.. the last one had two places - actually line 100 was the closing bracket of the function. Now everything working OK!
