Hello there!
Sorry to hear that you faced such an issue after the installation of our Hotel Booking plugin.
However, I wanted to let you know that we have not received any other complaints, similar to yours, from our customers. Therefore, it is unlikely that our plugin is responsible for the issue with your pages’ visibility. But perhaps something went wrong during the installation process.
Can you confirm that deactivating the plugin solves the problem? Also, do you have any multilanguage plugins installed on your website? If it’s okay with you, could you please provide some screenshots so that we can better understand the problem? Thank you.
