^{Originally posted by **jmaas-onoffice** January 6, 2023} > Time-tracking ticket: T#3442759 ## Empty array leads to problems Currently, when no estate is published for the website, the detail view shortcode can produce a warning [due to an array being empty](https://github.com/onOffice-Web-Org/oo-wp-plugin/blob/master/plugin/Controller/ContentFilter/ContentFilterShortCodeEstateDetail.php#L141): ``` Fatal error: Uncaught ValueError: array_rand(): Argument #1 ($array) cannot be empty in /usr/www/users/raumgu/raumgut_com/wp-content/plugins/onoffice-for-wp-websites/plugin/Controller/ContentFilter/ContentFilterShortCodeEstateDetail.php:141 ``` When using Elementor, this leads to a crash that makes it impossible to edit the detail page. ## Show link to documentation instead Currently, when there are estates available and the user visits the detail page without an estate ID (for example /detail), then we show this message:  When the user has no estates published for the website, we want to instead show the following message with a link to https://wp-plugin.onoffice.com/en/first-steps/estate-lists/. (The link should be translatable, of course.)

@jmaas-onoffice "The plugin could find any estates. Please make sure that you have published some estates, as described in the estate list documentation" => I think it must be "The plugin couldn't find any estates?", right?

Yes, you're correct! Thanks for catching that! :)

@jmaas-onoffice I fixed the message for the case no estate is published, you can watch and give me feedback.
