Totals not calculating correctly, plus other bugs.

Hi there,

1- The plugin never calculates the correct remaining amount left to obtain free shipping, especially when using % based coupons. I have paid for another plugin atm that works, even though I prefer your plugin, so if you are not able to fix this plugin I would like a refund

Also the plugin has many bugs:

2 – when viewing the plugin settings page and clicking on message tab, after some time the page freezes and can no longer switch between tabs and I get the cursor loading wheel on the screen and I have to close the browser window down. also get this error in the “announcement system” first text area field. Warning: Illegal string offset \’default\’ in /home/danie457/public_html/wp-content/plugins/woo-free-shipping-bar/woo-free-shipping-bar.php on line 270 Warning: Illegal string offset \\\’default\\\’ in /home/danie457/public_html/wp-content/plugins/woo-free-shipping-bar/woo-free-shipping-bar.php on line 270 Warning: Illegal string offset \\\\\\\’default\\\\\\\’ in /home/danie457/public_html/wp-content/plugins/woo-free-shipping-bar/woo-free-shipping-bar.php on line 270 Warning: Illegal string offset \\\\\\\\\\\\\\\’default\\\\\\\\\\\\\\\’ in /home/…/public_html/wp-content/plugins/woo-free-shipping-bar/woo-free-shipping-bar.php on line 270 Warning: Illegal string offset \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’default\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ in /home/danie457/public_html/wp-content/plugins/woo-free-shipping-bar/woo-free-shipping-bar.php on line 270 Warning: Illegal string offset \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’default\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ in /home/…/public_html/wp-content/plugins/woo-free-shipping-bar/woo-free-shipping-bar.php on line 270 Warning: Illegal string offset

I have deleted this error from the text field and now plugin works again and does not freeze, why would this error occur?

3 – the plugin should be using Ajax to show the notification information because when I add something to the cart is shows the information with remaining amount required to get free shipping, then when I go back to the home page, the standard message “free shipping on orders over $50” shows instead of showing the updated card information. The notification bar needs to override the website/browser cache, probably resolved using Ajax.

thank you and hope this can be resolved as quickly as possible.
