Drupal 7.x

My website seems to be down. I visit can load the home page and the few pages I have posted. Every page gets the following warning. I cannot log on, I get only a white page, and I cannot do an update.php. A little help would be appreciated.

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/s/h/e/shelton2/html/index.php:96) in drupal_session_start() (line 276 of /home/content/s/h/e/shelton2/html/includes/session.inc).

It worked and I had several test sites I was practicing with but today Quickstart quit working. I re-installed everything. No improvement: the drush create command makes empty website folders -- nothing inside the folders (/websites/"mysite.dev" contains nothing).

I removed every last file and directory from the drive I am using. I searched for stray files and eliminated everything I could find. (It is a new drive and I removed all files from it --it's MT)

I would like to create an image hosting/sharing site similar to imgur.com. Just a simple interface to upload images and then be taken to a page with information on embedding the uploaded image(s).

It would be nice to have the ability to drag and drop into the browser for uploads, and the ability to upload multiple files.

I would like this to be available for anonymous people, but perhaps have additional features for members or paid members such as lossless storage or increased image upload size.

Hi,
Can anyone point me at best practice documents for syncing content from a test Drupal environment to a live to a live Drupal environment. We have recently moved our website to the Drupal CMS but unsure of how to handle updates to live content. Our current thinking is that we make changes to the test and then sync those changes to live. Ultimately end users would make changes to test and and then every night update run some sort of sync process to update live. Is there a need for a staging server as well to sit between test and live?

drush quickstart-create --domain=test.dev makes a web page that doesn't open. It says file not found when I try to open it in firefox. The test.dev folder is empty when I look inside.

Any ideas?

How can I take and post a terminal screen shotfrom quickstart to this forum? Or post log records information in the log post area?

Thanks!

Is there a way to have a sign in page before the content is displayed? For example, the user clicked on one of the menu buttons then the sign in page appears, instead of having a sign in block on the field. Or is there a way only allowing members to access certain page.

All help appreciated
