Recent tweets and slider image getting cropped

Hello,
I have a few issues on my site www.roventix.com
The "Recent tweets" is not working. It asks me for the widget id, I don't have widget id, only twitter id. The twitter block is 2.0.

The MD slider image is getting cropped. See the image with persons sitting at the table. What is the correct dimension of the images.

The logos 179x89 and 209x104 pixels for regular and mobile respectively. Are there any issues with this ? It does not look like the logos are getting updated.
