Comments, Pages, and Themes all are not working

I am running a wordpress blog on an Ipower server located at
https://bryancloninger.com
I am using vistered little theme, nextgen gallery plug and widget, and add from server plug (akismet of course).

I noticed recently that I had no comments since I redid and upgraded my blog (which is not unusual since I do not post often – until recently)
When I try to comment on my posts, by clicking on no comments yet at the bottom… nothing happens.
I started clicking around and it turns out that pages are not working.
the little calender, pages, and categories when clicked on do nothing.
Also when I try to change themes (to see if it is the theme – though I do not want to change themes) does not work either. The preview window opens it says it is the other theme but looks exactly the same.
users can register, but cannot post comments.
Also the little background images and thumbnails were acting very strangely. I uploaded the two color images and thumbs and they did not work on a mac and firefox, but did on safari and explorer on PC. When I tried it again on firefox a few days later…bingo the background worked. But the default ones always worked.

I can only think of 3 reasons why this is happening…
1 because of an upgrade… though I doubt it, because I have another blog for my wife
https://www.annegiordano.net
that works fine….
2. because ipower had some problems with the install and so… at first it was installed on the root and then moved to bryancloninger/wordpress.
but I have updated since then and redone the database on mysql (cant find any php interface on the new vdeck control panel – the www.remarpro.com instructions for vdeck are outdated by a year)
3. there is a problem with the some database based on #2 (both figuratively and literally)

I just had my first baby and thus my blog is a busy place these days and it sucks to not be able to have comments working…

I wonder if I should just start from scratch… I would hate to have to rewrite everything and plug the galleries back in… (again)

this is the 2nd time I have had some goofy problem with ipower and wordpress. maybe it is my fault – so I am not blaming them. but I am frustrated. I have asked them for help – but I am not sure if they will be able to figure it out. time will tell…

I would be happy to do a favor for anyone who can solve this problem for me… Help Help Help ! pretty please with sugar on it.
