If you create a link and in the address you enter the string

\\

After you save the page is it not possible to edit the link and correct it. When the page is displayed (or edited), the "link" keeps the text format of a link but it is not clickable.

Repro steps:
1) Create a page
2) Insert a link
3) In the address box, type http://\\domain.com
4) Save the link and the page
5) Edit the page
6) It is not possible to edit the link

Please note that this bug may affect customers who try to paste a network location on Windows, as they have the form \\path\to\file.ext or file://C:\path\to\file.ext

Another way to make the link uneditable, and un-clickable:

• Use Insert > Link > Web Link
• Insert URL address with a "\" in the address

As a workaround you may try the following:

• Enable HTML macro to use HTML code within Confluence pages.
• Use 'href' to specify the URL in HTML macro.

  <a href="URL">text</a>
