I am a new user of WP. I investigated several themes for my website, and selected Twenty Twelve. I have successfully created a Twenty Twelve child theme, etc.
The only issue I have is that on login, my dashboard is not correct. It is trying to load the Pinboard dashboard. (This is one of the themes I looked at initially). This is happening in both IE 10 and FF 24 browsers.
While the Twenty Twelve theme was installed, I have installed, activated, deactivated, and deleted Pinboard. I have deleted and reinstalled Twenty Twelve. I have reinstalled, activated, deactivated, and deleted Pinboard again. I have today updated Twenty Twelve successfully. I have cleaned my browser cache.
All Twenty Twelve theme pages, including the child theme pages are working properly, save for the dashboard. I get unformatted navigation links to my web pages, and have to click on one of them to get to my dashboard navigations.
This webpage is not yet available online, so cannot include a link to it.
