Installing Drupal

Hi ,
I am working in a intranet site. Initially i was using og 1.3 in the development environment and the same og 1.3 moved to production. During development i "deleted" some og fields and re-created the same fields. In the first day of the production, i faced 404 error and the error solved after i disabled all og related modules ( including og_field_access).
Now , i want to enable og in my site, but , i am not able to disable the og.module ( it says fields are in use ).
Below are my attempts to make og works for my site.
1.deleted the og 1.3 fields & recreated the fields
2.override the og 1.3 folder in the sites/all/modules folder with the og1.4 folder
3.override the og 1.3 folder in the sites/all/modules folder with the og2.x beta1 folder
4.Did disable & uninstalled the og
5.removed the entire og 1.3 folder from my site and paste the og2.x beta1 folder.
6.deleted all og data from database

NOTHING WORKS FOR ME. STILL I AM NOT ABLE TO ENABLE OG (any version) in my site.
I am getting the below error/exceptions
1. Unexpected error,please try again later

Hey all this is my first post on Drupal ,
Question: Are there drawbacks to using an online drupal installation vs. a wamp. The online seems alot easier I got it up and running in minutes on webenabled. I havent tackled figuring and setting up a WAMP yet. Will I be missing out on something important if I skip this step and just use an online solution.

Hi, I'm moving website to a new server (from linux to windows - apache) (not mine, it is client's site). I'm moving website and db too.

But when I tri to open the new webpage I just get error "Connection was reset" (in browser).
I tried to empty cache_% tables in db but it did not help.

Any ideas?

Thanks

Is there any simple way to install this? I would rather write code than figure out how to install this...

Sorry if a bit of a basic question but my first install of Drupal, was going to do a multi-site install but decided perhaps simpler to get a single site one working first.

In my case which is the web root folder, is it:
/var/www/vhosts/mydomain.co.uk/subdomains/mysubdomain/
or
/var/www/vhosts/mydomain.co.uk/subdomains/mysubdomain//httpdocs

Thanks,

hello, I want install multisite .
when a user is registred,create a subdomain like :username.site.com
-Whether the sites folder should be separate ?
-Apache can automatically create a sub domain?
-I must use the Drush(site-alias) Or Domain Access module?
please help me or give a link for this subject.
thankyou
