Multiple Related Issues - Banners and Blocks

[furiousfurryfox]

I started working on banners today and have encountered multiple issues:

banner_block cannot be removed from layout - Settings in Layout section not being properly saved (if I refresh the page the banner_block shows up again sporadically).

Unable to delete banner_block from Blocks section or set status to 'Off' - Caused by blocks being detected as still in use in Layout, related to issue above.

I am working on default_html5, and have disabled AdBlock Plus and NoScript so that all scripts on localhost can run.

Do you have any layout related errors in AbanteCart error log?

Hi Basara, there are no layout related errors in the log. However I do have an App Error - Template default is not found - roll back to default in C:\wamp\www\abantecart_1.1.9\core\init.php on line 415 (dated from when AbanteCart was freshly installed).
