My First Template - Installation Errors - Need Help!

[Aenigmaticus]

So I've read variating tutorials with respect to creating ones own template. Cool! The template seems correct, albeit 'hello world'-esque simple, and should be compatible to the latest version of Joomla. All files are encoded with UTF-8.

File Directory:

aetherium.zip
/index.php
/templateDetails.xml
/css/
/css/template.css
/images/
/images/placeholder.txt (Windows Zip doesn't like blank folders)
/language/
/language/en-CA.tpl_aetherium.ini
/language/en-CA.tpl_aetherium.sys.ini

Unfortunately, when I try to install (Extension->Manage->Install->Upload & Install) I get this:

Warning
JInstaller: :Install: Can't find Joomla XML setup file.
Error
Unable to find install package

Isn't that part of the purpose of 'templateDetails.xml'? I've checked countless times to ensure the XML is properly formatted, and it is! I've also verified that the tags and layout is also correct with respect to the latest version of Joomla.

So what is this 'Joomla XML setup file' that it is referencing to? Is there a directory requirement I'm overlooking?

-----
Edit: I have also tried 'aetherium.xml' and 'manifest.xml', as per documentation. No luck unless I wrap the other files/directories into a 'template' folder, in which case it did 'install' and I got as far as setting it as the default template. However once I checked my home page to verify, the actual template defaulted to the System template; indirectly telling me that it is malformed. Odd!
-----
Edit 2: The template is meant to be a lean-and-mean HTML5/CSS with no Javascript in the frontend.

aetherium.zip
index.php
templateDetails.xml
/css/
/css/template.css
/images/
/images/placeholder.txt (Windows Zip doesn't like blank folders)
/language/
/language/en-CA.tpl_aetherium.ini
/language/en-CA.tpl_aetherium.sys.i

index.php and templateDetails.xml should be root of your Template so that it becomes
/templates/aetherium/index.php and /templates/aetherium/templateDetails.xml

[Aenigmaticus]

As per each template I've installed and tried, it was always contained within a compressed archive, such as zip. Correspondingly, the first '/' in each line defined is the root within the zip. Sorry for the confusion!

I learnt that the trial-and-error method, as mentioned in the first Edit.

Back to the problem -
Sorry for the original confusion, I'll reformat how I described the file layout:

Within archive file 'aetherium.zip':

• index.php
• templateDetails.xml
• css/
  
  • template.css
• images/
  
  • placeholder.txt
• language/
  
  • en-CA.tpl_aetherium.ini
  • en-CA.tpl_aetherium.sys.ini

Are you able to install other Templates ?

[Aenigmaticus]

Yes, I can install other templates.

Then check the syntax near the top of your templateDetails.xml

Code: Select all

Change

to
<extension version="3.1" type="template" client="site">
(Like it is in Protostatar's xml file)
