Drupal 7.x

Hi guys, relatively new to drupal and a PHP newbie.

My site is frozen in maintenance mode and is throwing errors relating to the file /includes/theme.inc.

I cannot in to the admin to change the template and test, etc. If I go to /?q=user, I do get the login but once the form submits I'm back to maintenance mode and errors.

Here's the site: http://kemek.org

Here's the errors:

* Notice: Undefined index: KMKorg in drupal_theme_initialize() (line 101 of /home/content/k/e/m/kemek/html/network/kemekorg/philanthropy/includes/theme.inc).
* Notice: Trying to get property of non-object in _drupal_theme_initialize() (line 146 of /home/content/k/e/m/kemek/html/network/kemekorg/philanthropy/includes/theme.inc).

Good day!
I can not understand how they can inherit the properties of field types when creating a new type of field.
For example, I have a standard field type "image" or "textfield". How do I make based on this new type of field with additional options and / or changed treatment.
I am sure that this is a standard mechanism, and the answer lies on the surface, but I can not find where to start

PS. I am a beginner
PPS. Sorry for my english

Where is the update page in D7?

Hello,

I'm just searching out how can we display the related node/content in a search result page in Drupal; for eg. we wanna display the related node/content in terms of fields like location? How can we achieve that?

Okay, I'm lost here with the WYSIWYG API...I installed the WYSIWYG API, installed TinyMCE and ckeditor and WYSIWYG API recognizes them so I set them to be my default editor then it work normal but when i submit or save it doesn't work. (Everything is unknown HTML tags.

what am I missing?

Thanks
