Error: “Template is missing.”

I too have been trying to create a new theme entitled “ejm”. I believe I have followed the instructions at

http://codex.wordpress.org/Theme_Development
http://codex.wordpress.org/Upgrade_1.2_to_1.5

In the ejm file, there is an image, comments.php, index.php (that is a direct copy of the index in my new default folder) and style.css

index.php has been updated to replace <code><?php echo get_settings('siteurl'); ?>/wp-layout.css and <code><?php include(ABSPATH . 'wp-comments.php'); ?> with
<code><?php bloginfo('stylesheet_url'); ?> and
<code><?php comments_template(); ?>

at the top of style.css, I have added the required top section (for this forum, I have changed the URLs)

/*
Theme Name: ejm
Theme URI: http://myblog/
Description: (this theme was a heavily modified version of pollux)
Version: 0.1
Author: ejm
Author URI: http://mydomain/
Template: Pollux that was based on gemini
.
The images (which must not be altered in any way) used in this theme are strictly for non-commercial use only.
.
*/

The theme files are in wordpress/wp-content/themes/ejm

This is the message that is in my admin file:
ejm Template is missing.

What file(s) have I missed uploading?

Try deleting the “Template…” line.

No, the original pollux has this:
/*
Template: gemini
Theme Name: Pollux
Description: Warm yellows and browns, ever so slightly inspired by the <a href="http://textpattern.com">Textpattern</a> admin interface.
Author: not (that) ugly
Author URI: http://not-that-ugly.co.uk

Odyssey interface and Gemini template for WordPress 1.3 designed and built
by Root http://www.atthe404.com/blog/. Mutilate however you please. Credit not required but always welcome, unless you make the thing neon green.

which means it doesn’t have its own “main template” (index.php) so it uses the gemini’s index.php. All the so-called ‘parasite’ themes are using files from other themes and in that case you have to define which files are to be pulled.

I stand corrected moshu. I did not at all understand how that template worked, nor did I understand why I had to have the gemini folder in 1.2.2. I just put it there when I installed the pollux theme. When I moved the pollux stylesheet over, I left the template descriptive there thinking that it was a credit to the original author of the stylesheet template… I guess I added the “gemini” part to it.

I’ve now moved the gemini/pollux credit down into the notes below the version number

Root, thank you for reiterating moshu’s explanation.

Root; would you like me to remove any mention of gemini on my stylesheet? I haven’t examined the gemini stylesheet to see how much of it is still retained on what I have now….

I’ll leave the gemini name on then. The things that I have changed are colours, images, widths (it’s dynamic width now rather than fixed) but I would never have had the patience to do the whole thing from scratch. I’m glad you did though!
