Undefined index: base theme

Same here but in 6X as well

same here.

Error
Notice: Undefined index: base theme in system_find_base_themes() (line 2564 of (site specific path then...) /modules/system/system.module).

Do you have a subtheme of Fusion core enabled as the default, or do you have Fusion core itself as the default? Fusion core isn't meant to be a theme by itself. Regardless, I'll take a look at the error.

I can replicate this in 6.x, with a subtheme enabled as the default. The error seems to persist whether fusion_core is enabled or not

I have the same problem here but with orange theme. I suspect that it is because of the skinr module. The snippet that is likely to cause the problem is

skinr.module

function skinr_preprocess(&$vars, $hook) {
  ......
  // Add any base themes. 
  $themes = array_keys(system_find_base_themes(_system_theme_data(), $current_theme));
  // Add the current theme.
  $themes[] = $current_theme;
  ......

system.module

function system_find_base_themes($themes, $key, $used_keys = array()) {
  $base_key = $themes[$key]->info['base theme'];
  // Does the base theme exist?
  if (!isset($themes[$base_key])) {
    return array($base_key => NULL);
  }

Can we move this to skinr module issue queue ?

problem solved!

#6 (Kinesus), How you solve it?

I've only been able to recreate this error if Fusion Core is set as the default theme, instead of one of its subthemes. Could you provide more information so I can replicate/debug the issue?

I tested and in my case (fusion 7.x-1.x-dev) installing a subtheme and setting it as default solved this problem. This is the case for both with or without Skinr (7.x-2.x-dev) installed.

I fixed it by doing this fix in system.module, its a quickie, but it solves the problem, even when using fusion core as main theme. Therefore you dont need subtheming to fix this issue.

function system_find_base_themes($themes, $key, $used_keys = array()) {
$base_key=NULL; // added by arne@hortell.se
if (array_key_exists('base theme',$themes[$key]->info)) // added by arne@hortell.se
$base_key = $themes[$key]->info['base theme'];
else // added by arne@hortell.se
return array($base_key => NULL); // added by arne@hortell.se
// Does the base theme exist?
if (!isset($themes[$base_key])) {
return array($base_key => NULL);
}

After upgrading the system_find_base_themes actually calls
drupal_find_base_themes

But the old problem code above still exists...
Here is what the start of it should be
---------------------------
function drupal_find_base_themes($themes, $key, $used_keys = array()) {
$base_key=NULL; // added by arne@hortell.se
if (array_key_exists("base theme",$themes[$key]->info)) // added by arne@hortell.se
$base_key = $themes[$key]->info['base theme'];
else // added by arne@hortell.se
return array($base_key => NULL); // added by arne@hortell.se
-------------
Rest is untouched...

Changes above is done in
drupal_root/includes/theme.inc
at lines 841 and forward.

It turns out that fusion/fusion mobile has an issue so its not necessary to do the above fixing, just remove fusion themes...
