I have a problem with my store Abantecart.

Error: Error in data of page with controller: 'pages/content/content'. Please check for key_value present where key_param was set

How can I resolve this error?

There is something happened with layout for this page or all content pages. 

Try to clear cache first.

Next go to layout of these content page and update something and save. You can start with generic layout for content
