Dear support team, we encountered the following issue.
addons-for-visual-composer/freemius/start.php 

After we finished editing and building the website project we migrated it to another hosting provider and assigned new domain name.
The developmental address is: http://hib.estillo.eu/
and the Official address of our website is: https://iglikaborovets.com/
So you will see that there are a couple of errors/warning regarding the visual composer plugin. We do not understat what is the reason for the issues.

Also we can not access /wp-admin for the official address: https://iglikaborovets.com/wp-admin beacuse of these errors.

If you are not able to access the link: https://iglikaborovets.com/, please add this to your host file, so you will be able to access it, because of the DNS sync proccess.
185.45.66.104 iglikaborovets.com www.iglikaborovets.com

We would be very glad if you assist us with some solution for this case.

Best regards and I'm looking forward hearing from you!
Thank you!

Thank you for the response! It was very helpful! We would like to make one final customization, when we load the website via mobile phone or tablet, the design is responsive, which is okay, but we were unable to find a way to hide, disable or remove the section for "Member login" - we do not want to make login or registration to our customers and also the section "Reservation" - in the attached files you will see a marked sections by us.
Maybe there is some settings panel, that allows this but we could not manage to figured out.

Best regards!
