Post installation

I have created several groups for people and have successfully subscribed them to the group. I now want to make them the group manager and I want to unsubscribe myself. How do I do this? I've looked on the site and tried to find where it might be in the administration, but I can't find it.

Thanks,
Laura

Situation:
I have created a text site www.example.com/testsite. I added a few pictures with TinyMCE.

Issue:
When the site is moved to www.example.com the url's are pointing back to www.example.com/testsite.

Everything works fine but If I request a non existent page I get an error 500 and not the usual error 404. Anyone can help? I have the .htaccess default file.

Does anyone know why node dates in a Recent Blocks list would come out wrong? I mean bizarrely wrong: they all come up "36 years 35 weeks ago". They're actually several days old...

I'm having a problem with images and 4.7.3 which I installed a couple of days ago. My thumbnails and images don't show but the files are in the files/images folder as they should be and their paths are correct (as are the paths written into the database). I've checked the HTML code and the paths are seemingly correct also. Clicking on where small icon that is produced instead of the thumbnail leads to another missing image icon where the image itself should be. Does that not sugeest the paths are ok?

Hi, I have set a bunch of categories that are meant to be used for articles only. Now I have a content type that can be created by any user, but I don't want my users to be able to select a category for this type of content, so that these items wont show on the pages of my taxonomy menu navigation.

Can I do this?
