Illegas string offset

Hi,

Thanks for your plugin. It’s very useable. However, after updating to the last version, when not having added any images yet I get this error;

Warning: Illegal string offset ‘checked_taxonomies’ in /xxx/wp-content/plugins/wp-custom-taxonomy-image/wp-custom-taxonomy-image.php on line 15
To me it seems as if I get this error since
$aft_taxonomies = $options[‘checked_taxonomies’];
ends up being empty (maybe due to the fact that I have this plugin installed and network activated – not all our ngo:s use it, but it’s on other plugins depends on it)

I did this;
if(!empty($options)){
$aft_taxonomies = $options[‘checked_taxonomies’];
}
