Fatal error: Call to undefined function phptemplate_default_theme_settings line 35

Also I am not sure if this helps, but below is a list of error I was getting on the blocks admin page in reference to the themes, but then I switched to Marvin as the default and back to Acquia Slate the errors on the blocks page went away.

I still am receiving the Fatal error on line 35 though.

Thank you,

I confirm that I have template.php in the Acquia Slate theme folder.

I have attached the template.php file I have uploaded to my site.

I confirm that cache is disabled and the cache data is cleared.

update:

I switched my admin theme to chameleon, the marvin template errors are no more, but I am still getting the Fatal error when trying to configure Acquia Slate

Fatal error: Call to undefined function phptemplate_default_theme_settings() in /home/public_html/drupal/themes/acquia_slate/theme-settings.php on line 35

thank you for your help

yes this happened right after the last update.

But alas, I am not using: /sites/all/themes/

I have only installed the theme at: /themes/acquia_slate

Hey jwolf & illepic, thanks for your help with this. Please be patient with me. This is my first real attempt at producing a site with Drupal. Overall I am really impressed with the capability and support Drupal has. What makes me nervous is the only problems I have had, only came after installing the required updates. I am hoping I can get the few issues I am having worked out so I can really be a part of the Drupal Community.

------------------

My fresh install of Drupal and Acquai Slate did not have the fatal error problem either.

However, when I recently updated from Drupal 6.10 to 6.12, and updated Acquia Slate to 6.x-2.x-dev, the error and another major error with ImageCache Profiles became evident. (You can see my issue with IC.P. here: http://drupal.org/node/482630). Because I already had everything working together nicely, and both problems happened right after running the updates, I can't help but wonder if they are somehow connected.

The last thing you asked me to do was to "check the permissions of the theme's files on your server". I have done so, and the permissions are set at 755 (which appears to be "world-readable")

Please let me know what else I can do? I feel a little lost here.

thank you!
