Drupal 4.7.x

Greetings,

I have three Drupal-based sites I've built for clients that I don't have the time to maintain properly. Two of them require minor maintenance (usually less than 2 hours/month). The third is a different situation; their in-house web person has left, and they would like me to be the go to guy. I have a full time job that is taking up more of my spare time, and I don't have the time to properly give them the assistance they need.

Have been using Drupal 4.7 for about 1 year.
Stopped logging in for abt 1 mth and then few mths ago when try to log in encountered this login / permissions problem:
-Can login in using super administrator username and see all functions/ menu but when I click a function, it shows error "Access denied
You are not authorized to access this page".
-Then I login again and can see all the functions but when I click for eg. Create content it comes up with error "create content

I wanted to post this because I keep forgetting how to do it and would like my own quick reference, and because others might find it helpful.

So....if you're on a Mac and uploading lots of files to your drupal site (modules, photos, etc) the easy way is to upload the tar.gz file and unzip it on the folder.

I installed 6.4 in a subfolder to test it. I belong to those idiots, who do not take backups: from now on, I promise to make them regularly. When I deleted the 6.4 installation, I accidentally deleted the settings.php file of my production site, which is 4.7.3.

Somebody asked me today whether there was a way to have the theme of a specific page be determined by the referring URL. So for instance, if somebody arrives at Page 1 from Site A, they'll see Page 1 skinned by Theme X. However, if they arrive at Page 1 from Site B, they'll see the same content in Page 1, by this time it'll have Theme Y applied to it.

I know Taxonomy themes will allow you to use multiple themes in a given site. But is there a way (even in theory if not in practice) to permit there to be multiple themes for a given PAGE, determined by the referring URL?

I am studying CMS, and currently looking at 2 in detail to compare.

Would somebody be able to help me to compare the difference between SHAREPOINT 2007 and DRUPAL and tell me which CMS is better. I know that SHAREPOINT 2007 is for ASP.NET and that DRUPAL is for PHP, but besides that I would like to know the difference, in for example, which has the best SEO(search engine optimization) features.

I am new to this so a simple explanation would be grateful. Thanks in advance.
