Upgrading Drupal

I'm having problems after upgrading to 4.7.6. Most of them (theming, etc) I've managed to resolve, but I can't figure out what's going on with two contributed modules, or with a search box I've put in my theme.

Webform and Sidecontent are both having the same problem. When I view pages with forms on them, I can see the form. When I view the pages with Sidecontent, I don't see the sidecontent.

Then when I Preview a webform pages, I can see the form; when I preview a sidecontent page, I can see the sidecontent. BTW, these are not the same pages.

I am trying to upgrade from 4.7 to 5.1. I tried it on my production installation, which failed miserably (hint: BACK UP YOUR DRUPAL SITE BEFORE UPGRADING or you may live to regret it! I was able to restore my 4.7 installation.

Next, I used the backup files to set up an identical website on my pc. I was able to upgrade on my PC without trouble.

The GUI upgrade instructions, are they fully completed? To me it almost looks like a joke, expecially the line "any other files you need from the 'backup' directory". I'm a beginner so I have no clue which other files I need.. Did the three first steps and got to the point where my site is in the first installation steps and want's me to enter the database location and information. Will this ruin my current database content?

I'm upgrading from Drupal 4.7 to 5.1. I've backed up my database just fine, but backing up my Drupal Files has been very confusing. The main problem is I can't seem to find much information on the subject. I've seen the stuff provided in the handbook and didn't find it too helpful unfortunately.

I'm using a Windows Command Line Shell (Start -> Run -> "cmd".) All I need is are good, precise, step-by-step directions on how to make a backup of my existing Drupal directory.

Thanks in advance!

So i received my email about the security issue.

I started looking for instructions. All I can find it "here is the patch, enjoy".
I look at said patch, it makes little sense to me whatsoever. I have a website, it's hosted (not by me) and I don't have a clue as to what I am supposed to do with the patch. I also haven't located (it may exist, but I haven't found it after 10 mins of looking or reading for it, but I am not familiar with this sites layout as to intuitively know where to look) any instructions on how to use it!

I would just copy up the full release instead, but what about my database settings? I can't find which file contains the settings about database access... no idea why! Would i need to copy files like "update.php" and "install.php/sql etc etc"

I like how drupal looks, but at the moment I just cannot help but feel things are so much easier with other CMS systems, and that Drupal is neither intuitive or simple to upgrade. I can only imagine I am missing something significant somewhere, there must be a more simple way that i can't see -- therefore I am asking a question.

I attempted to upgrade my 4.6 site to 4.7 and then 5.0, but it's now completely broken.

I think that if I am able to change the theme I can get it back. I can't view blocks right now, so I have no way of changing it from the web. Can anyone PLEASE tell me what setting I need to change in the database in order to set it back to the deafult theme?

Thanks,
Ted
