Question

1C-Bitrix

Question. There is a website dublinhotel.ru powered by Bitrix. I needed to change my phone number on the site. Changed. After the change on my computer, the site stopped opening in any browser with an error

[ParseError]
syntax error, unexpected '\' (T_NS_SEPARATOR) (0)

The site works on other computers, the site opens on the phone. It's been that way for over a day. The phone number hasn't changed, by the way. The question is, what kind of magic is used here?
Moreover, there is nothing at all in the hotel.php file on the 12th line.

Remove one plus in the message HOTEL_INFO ->
<a href="tel:++79531063288">...</a>
<a href="tel:[phone]">...</a>
