Post installation

I installed Drupal yesterday with no problems. I installed my theme, a few modules, and all was well. Upon loggin in today, I was taken to a blank page at node?destination= . I have read a lot of posts on here about this, but I am SOOO new to PHP and databases that I do not know where to begin.

Background: Commented out some lines in order to hide the ical icon in events module as suggested here:

I'm experimenting with modulle taxonomy_breadcrumbs.

When I go exactly to the node I see (e.g. in ?q=node/1) the bread cumps starts with the text defined in the settings of the modulle. But when I click the taxonomy therm of the node I get to, e.g., ?q=taxonomy/term/1. But at that page the bread cumps starts with obligate Home whatever you set in settings.

Does it meen that the modulle modify only bread cumps for nodes or it is a bug? Or it is another mystery of breadcumps? ;]

I'm not sure that I understand the strategy how are bread crumbs generated (so and how to deal with them).

When I visit a node, e.g., ?q=node/1
I get breadcumbs: Home » content

In fact, how and where is defined that node is represented in bread crumbs by content? How can I change it?

There are more questions ... but in fact I cannot formulate them exactly (cause I donot get a idea of philosophy of bread crumbs). I probaly expect som comments then the complete answer.

Hello

In the comments section of my blog, the form asks for name, email, website and the comment itself.

How do I make it so that once a user has entered a comment on my site, the next time he visits my blog, the first 3 form elements are automatically filled? (I have seen this happening on wordpress...)

Is this a browser feature? Or Drupal saving cookies on the comment poster's website for future reference?

Hi, I've posted my question about this exhautively, but have yet to receive a response ...

I accidentally erased all audio MP3/video files uploaded through the audio module from my database, but the META data still remains. Meaning, the audio/video is gone, but you can still browse by name of song/vid clip, artist, title, etc. -- it's just that there are no audio/video nodes corresponding.

How do I erase EVERYTHING (including the META data) andre-upload the audio/video from scratch again?

Hello all. This is a tinymce customization question.

The module is set up to pull the css from the theme. The sites layout features a blue background with the content over a white background. In tinymce, the background is the blue background. How can I override the background of tinymce to be white?
