Please, this is urgent!! My plugin stopped working after latest octobercms update. I get this message when I try to create a post.

"Call to undefined method October\Rain\Database\QueryBuilder::formatHtml()" on line 2101 of /var/www/****/public_html/vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php"

Also I can see an 500 error

jquery.min.js?v361:4 POST http://*************/backend/radiantweb/problog/posts/create 500 (Internal Server Error)

I have disabled all other plugins, tried a fresh install of plugin with no luck. My current System build is 361

Thank you for your help

Update: I've located the method which is not working. It's in the problog\models\post.php file, at line 132.

So it seems, that this error happens only when markdown is selected. Plugin is working, but hope someone will fix this issue soon. Thank you
