Hey @dessainsaraiva,
The shortcode seems correct unless you are copy/pasting it and you have “special quotes” – you can try just deleting and manually re-typing [ecs-list-events venue='true']
and see if the venue appears there. Also ensure the event(s) have a venue saved against them (which is why it’d be good to see a published page with the shortcode added).
There’s the possibility that another plugin or your theme is causing the venue to be hidden. You can determine which plugin or theme is causing the issue with the following steps:
1. Ensure you have a backup of your site in case there are any issues when disabling/enabling plugins or your theme
2. Disable all plugins (except your calendar plugin and this plugin), and switch to a default theme like Twenty Sixteen then verify the issue is resolved
3. Re-enable your plugins and switch back to your previous theme one by one verifying if the issue is still occurring, and note which one causes it to break
Let me know which plugin/theme causes the issue and I may be able to come up with a fix, but you’ll also need to contact the theme or plugin author and have them fix the issue.
Cheers!
