In forum page appears this shortcode – [wesf_account_page] and anymore.

What is it? Why appears only this? what is missing?

I have no idea nor could find a reference to [wesf_account_page] most likely it is a plugin.

All references to it via a Google search appear to all revolve around a page titled my-account.

Most likely it was from either a theme or plugin you no longer use as you see the ‘raw’ shortcode rather than a rendered shortcode. Find what page the shortcode is used on and remove it.
