WordPress not adding captions to my images

Question

I've been trying to add a caption to media I'm adding to my posts but when I insert the image it just inserts the image tag and the caption as 'alt', like so;

<img src="url" alt="the caption" />

instead of:

[caption id="attachment_6" align="alignright" width="300" caption="the caption"]<img src="url" />[/caption]

I'm using the latest version of wordpress and the twentythirteen theme.

Thanks in advance.

Answer 1

I guess it is related to your theme coding. Try using this shortcode: [caption width="600" caption="A football video"][embed]http://vimeo.com/14580921[/embed][/caption]

put caption into embed

And try switching to the default theme.
