In Howello theme, on Room single pages, there is a contact form for quick contact on right side. As seen below.
After importing demo, you might have seen an error code as seen below.
[dynamictext dynamictext-634 "CF7_URL"]
To fix this issue, you can either remove above line from contact form by going wp-admin/contact
Or you can make this Dynamic text work, it displays the URL of current single page dynamically.
To make it work, please install and activate this plugin.https://wordpress.org/plugins/contact-form-7-dynamic-text-extension/
After installing this plugin, the Dynamic text field will work automatically by displaying the current page Link. So when user submits the form, you will know which Room (s)he is inquiring about.
