We've put in a shopping cart for a client that's not working, and we need some help!

The cart is currently using the WP-ecommerce plugin. Even the developers of this plugin admit this thing needs to be scrapped and rebuilt from scratch. Yeah. Anyway, the products on the site require a very sophisticated level of functionality that affects shipping based on country and zip code.

We've hacked the plugin to pieces to make this work, and there are still errors that are costing her sales. It would be easy to limit shipping on a product-by-product basis, but that's not the way her store works. Like on Cafe Press: I want the slogan that says "My mom can beat up your dad." Once I select the slogan, I can choose to purchase that slogan on a t-shirt, mug, or bumper sticker. However, if I live in London, I shouldn't even be offered the bumper sticker, for example, since it can't be shipped.

See our problem? Got any WordPress solutions for us??

I have two accounts set up for my WordPress blog and I'd like to be able to have all my posts from a single account. Every so often I forget which one I'm logged in as, however, and post as the wrong WordPress user. Is there a way to change authors after the fact?

I have a wordpress blog that was using categories in the url structure like this:

/category_name/post_name/

Then I had read somewhere that if you change it to just /post_name/ that it will automatically redirect the old to the new.

It does that, however, somehow Google Webmaster Tools is reporting both and giving us warnings about duplicate title tags, etc.

Do you have a solution for that?

I really like the set of social media buttons you have on the pages of your AskDaveTaylor site, Dave. What are they, and how did you add them to your site? In particular, a lot of the ones I've looked at have uninteresting sites like Delicious and Reddit, but don't yet support the new Google Plus "+1" button, so yours is really slick. What's the story?

I notice that sometimes on the Google search results that the author of the article is displayed next to the match in the search. Sweet. How do I do that? Is it tied to the addition of the new rel=author attribute?

I've been diligently working on my blog for a year or so now and am getting some decent traffic but I'm still curious about where I can expand and grow with an interest in better serving my reader base and gaining even more traffic. One thing that's caught my attention is the search on my site. Specifically, I realize that there's no way to know what searches people enter on Google that should lead them to my site, but what about when the search is actually on my site? And more importantly, what searches could they be doing that produce zero results? Is it even possible to figure out empty search results on my blog?

I've been inspired by your Facebook fan page, Dave, and have one of my own. Now that I have it, though, I'd like to be able to inclue a "like" box on my blog so that people not only see a link to the fan page, but see a few members, etc. I have seen it done on other blogs but can't figure out what they did. Is it a Wordpress plugin?

A friend pointed out to me a few days ago that if I were to have a data hiccup or have my system crash that I could lose everything I've ever written - and what everyone else has added as comments - from my Wordpress blog. Definitely not good. Is there some easy way to back up my blog so that I can insulate myself from this danger?

As a contributing author to a weblog about South Africa's upcoming World Cup 2010 (see The South Africa Project) I was rather surprised the other day when I went to log in to our Wordpress blog, just to see the following warning in my Web browser:

What does it mean? How can we get this sort of warning from our own site, without ever opening up anything or getting any indication that we'd be hacked or compromised?

I've been using Movable Type almost as long as you have, Dave, and just noticed that the way you name your blog entry archives is pretty different to how Movable Type 4 does it by default. I'm setting up a new blog for my sister and would like to see if I can mirror your archive filename format. My question is: how do you change the template file naming scheme in MT4?

I've been using Wordpress for a while now and it's very easy, which is cool, but I want to branch out and start including photographs and other graphics in my postings. I tried dragging and dropping images onto the edit window and it was a fail. How do I add graphic pictures to my blog entries, Dave?

I have heard you talk more than once about how you write blog entries and schedule them for future publication so that you can space things out and work ahead, rather than having to create a new blog entry every day. Nice, but how do I do that in Wordpress?

A person named Kavita posted a comment elsewhere on my blog that stated: "my site is activated from google adsense i m unable to paste code in website i tried many times but i failed can u help plz?" It's a much bigger problem than a bad cut and paste, however, and something critical for people running AdSense to realize...

I have a wordpress site. My challenge? I wish to have my home page display only my latest 5 entries, yet want to have categories for my blog (when clicked upon) display all of the previous posts for that category, not just 5. I am not a programmer so I don't know or understand much about coding. However, I have been told that this is not possible. Is that really the case? Is the program as inflexible as this? Or is it just a matter of taking time to program in a different number of posts for the homepage versus the other page displays.

I just purchased Growing Your Business with Google and can't wait to start reading it. Here's my questions. What are the major differences between Blogger and WordPress and why would I want to use one rather than the other?

Dave, I host my images on my own server, but I hate using some of the more primitive tools to work with it, especially FTP. So, tell me, is there a way to add images to my blog entries if I'm using Wordpress without using the file transfer protocol software?
