Thread:Project:Support desk/Various issues with customizing

I'm having a series of issues with my MediWiki customization. I'm using the gumax skin, and currently putting everything together offline using MAMP, so I'm not sure if this is causing any issues. I'm also transferring setting from old LocalSettings.php file (running on older mediawiki installation) to new LocalSettings.php file (runnung 1.17 installation).

Issue 1: I hard-coded a log-in link into a new navigation menu, and it points to /index.php?title=Special:UserLogin. When I login, the page redirects to /index.php?title=Special:UserLogin&action=submitlog in&type=login, but this page is blank. I have to manually go back to index.php/Main_Page to see the content of site. Any ideas on a fix for this?

Issue 2: /mediawiki/index.php link doesn't show default homepage. I have to navigate to index.php/Main_Page in order to see homepage.

Issue 3: The Table Of Contents limit template is not working for me. All the subheadings are appearing.

Issue 4: Once logged in and click on the My Preferences link, there are no tabs for customization on the following page. I've attached a file that shows what I'm talking about.

Thanks for the time and help in troubleshooting. I have done some initial research through Google, but haven't been bale to find any solutions. MediaWiki is beyond my area of expertise, but I would like to know how to fix these crucial errors.
