I've got a clean install of 8.1.7 with bootstrap-8.x-3.x-dev installed. With 'Bootstrap 8.x-3.0-rc1+12-dev' installed and set as default the homepage looks ok, but if I go to Appearance->Settings I get the following warning:

Title: Illegal string offset 'bootstrap' in Drupal\bootstrap\Theme->getPendingUpdates() » The "schemas" setting should provide a default empty array value

While, I cannot reproduce this with a clean install of 8.1.7 and the latest dev... I can kind of see how this came about.

I can only assume that you didn't actually do a "clean install" and instead just updated bootstrap to the latest dev.

This would make sense because the setting changed from schema to schemas, thus:

$schemas = $this->getSetting('schemas'); would return NULL if you already have settings for the theme in the config.

Will commit a fix here shortly.

Ah! I just saw this error :D

Turns out this only happens when you click "Save configuration" on the settings form. Basically, it was saving the hidden value on the form (which is a string), thus causing the error above.

Went ahead and fixed it in the above commit.
