Alternatively you can manually download each file one by one.

The installation is the same as for any other theme though, just upload it into the themes folder and it will automatically appear in your list of available themes in WordPress.

No need to do a special "install" I have loaded about a dozen Themes in the last two months for testing, none using the Theme Installer - I just grabbed the zip file - unzipped it and loaded the whole directory up with FTP into the Theme directory and they magically appeared in Dashboard >> Themes.

The only caution is to get the name of the Directory correct, I suspect a spelling error might not be the best.

HOW do I download the theme. I can see those files. Presumably I can download them to my computer. Presumably, then, I can upload them again via FTP. But you're dealing with somebody who goes to the Theme Installer, searches for a theme, clicks Install Theme and considers that a hard day's work.

Should I just hit google for this? Or is there a workaround?

This sort of theme is fairly simple. There's not a whole lot going on under the hood, so I wouldn't expect much in the way of future problems, at least not for a few years anyway. WordPress is pretty good at providing backwards compatibility and you need to do something pretty dumb ass for it to break on an upgrade - or complex, which this theme is not.

There's potentially a depreciated function or two in there, but that's likely to cause a catastrophic crash in there if it gets removed from core WordPress and so it will tell you which file and line the problem is. Then you just need to download a fresh copy and either copy ALL the files over like I suggested above or you could find the changes in the new version and apply them to yours. Either way, any problems should be simple to fix I would suspect.

That said, thanks for all the info. I feel much better about this and may give it a shot this weekend.

The theme looks pretty basic. I'd guess it will keep working for a long time to come and presumably it will be here on WordPress.com so they'll need to upgrade it anyway.

Or at least you can't download it directly via a zip, but you can check it out via subversion or copy each file out individually.

If it works fine, why don't you recommend it?

There were security issues with it. I sent a security report though last night and those holes have now been patched by WordPress.com staff so it shouldn't be a
problem any longer.

I really wanted it to work for my photoblog, but I'm not going to be doing any serious theme hacking. I have enough on my plate.

These things are never simple.

There's some nasty looking code in there though so I wouldn't recommend using it.

I’ve given up on releasing “versions” of Hemingway. You’ll just have to download the latest version of Hemingway for Wordpress (zip) from GitHub. It’s been tested with Wordpress 2.7

Looking for Hemingway support?
Check out the support forums.

If you’d like to contribute to Hemingway, please do check out the GitHub repository. Patches welcomed

As for what causes errors, that varies with the theme. You can't generalize. Let me give you an example: Duotone is a photoblog theme. Unless you substantially hack the code, if you install it and use it on your blog, it will not display your photos at all.

Look at Hemingway: it's not available for download anymore.

Yes it is. It's available in the SVN repository I linked to earlier:
http://svn.automattic.com/wpcom-themes/hemingway/

The other thing is, some .COM themes are problematic on.ORG blogs since they have features and additions that are only compatible with .COM blogs.

Do you know what specific features tend to cause problems?

I've never found one that I didn't have to tweak before launching it on a .ORG blog.

Not all themes at WordPress.com are available for external blogs</blockquote.

I don't believe that is true. There is an SVN repository of (what I assume is) all free WordPress.com themes here:
http://svn.automattic.com/wpcom-themes/

What I meant was that there are a "Lot" of themes at wordpress.org and wordpress.com that have the exact same look and were designed by the same company.

I was using the "Enterprise" theme at wordpress.com and so I was wondering if anyone knew it it was also created for wordpress.org because I couldn't see it there?

The themes found there are coded to run on our software at wordpress.COM and are not the same as those coded to run on wordpress.ORG installs because wordpress.ORG installs run on different software.

Please, please read these support entries so your clearly comprehend that there is no FTP access to wordpress.COM blogs and we cannot upload themes into them. And so you clearly comprehend all the differences between wordpress.COM blogs and wordpress.ORG installs.

If you want complete control over your blog and the limitations of having a wordpress.COM blog do not suit you, then the solution is to hire a web host and get a wordpress.ORG install.

Thanks
