Based on your update about the possible source of the conflict, I’ll keep the plugin active in my test environment to see if it occurs. * In the meantime, when the error comes up, does it disappear on its own, or are there extra steps you take to clear it? * However, I’d also recommend switching from the [sc_events_list] to the new [sugarcalendar_events_list] shortcode as outlined in the [shortcode guide on displaying upcoming events.](https://sugarcalendar.com/docs/displaying-upcoming-events/#shortcode) * Could you please try this and let me know how it goes. * Thread Starter [Attila Zoltán Kedei](https://wordpress.org/support/users/attilazkedei/) * (@attilazkedei) * [8 months, 1 week ago](https://wordpress.org/support/topic/shortcode-error-38/#post-18662664) * Ok, but [sugarcalendar_events_list] is doing something different and I just want to have the original mechanism. I just discovered, there’s a bigger problem when I have sugar calender lite and Slim SEO switched on. My pages menu gets scrambled. You can try to recreate it the following way:Have sugar calendar lite (3.9) and Slim SEO (4.6.2) ([https://wordpress.org/plugins/slim-seo/](https://wordpress.org/plugins/slim-seo/)) both installed and turned on.Have more than one page in the pages menu and the first page should contain [sc_events_list display=”upcoming” order=”DESC” number =”6″ show_date=”yes” show_time=”yes”] somewhere. I use the standard gutenberg editor. In the meta desc. data column of the first list item, instead of showing the data there’s going to be an error message and no other pages will be listed afterwards.This happens **only** with the [sc_events_list] shortcode, switching to [sugarcalendar_events_list] would solve it, I just need to figure it out how to make it a clean list without the mini tools.I’m going to post this same issue on the other plugin’s support page as well. - This reply was modified 8 months, 1 week ago by [Attila Zoltán Kedei](https://wordpress.org/support/users/attilazkedei/).

Could you update to the latest version (3.9.1) and let me know how it goes? * Regarding the original concern on the shortcode, with the new shortcode option, you should be able to achieve a simple and minimal layout using the following shortcode. * ```wp-block-code [sugarcalendar_events_list display="plain" show_block_header="false" allow_user_change_display="false" show_filters="false" show_search="false" show_date_cards="false" show_descriptions="false" show_featured_images="false"] ``` * Would you mind testing it out once more and letting me know? If you’d like to further adjust or remove some of the other functions on the list, do let us know. * In case it helps to share, I also tested the setup using the legacy shortcode you had shared [sc_events_list display=”upcoming” order=by number=”6″ show_date =”yes” show_time=”yes”] and this worked as expected. * I’m looking forward to hearing from you. * Thread Starter [Attila Zoltán Kedei](https://wordpress.org/support/users/attilazkedei/) * (@attilazkedei) * [8 months, 1 week ago](https://wordpress.org/support/topic/shortcode-error-38/#post-18668446) * After the update I can create new pages in the pages menu. Great! But the page listing still gets blocked by an error caused by the old sc_ shortcode when Slim SEO is also present.Maybe it’s not sugar calendar’s fault I don’t know, but are you going to take a look
