Manual talk:Running MediaWiki on macOS

We are getting a strange error, after the wiki was running fine for a while. Now, external users get a DNS error saying that

If one tries to go to our site at: http://barracloughltd.com/mediawiki

the following error comes up: It can not find http://barracloughltd-com.local

in other words, the .com is changed to -com and the /mediawiki is changed to .local

What is that all about?

If anyone has any ideas please let me know. Edward M. Roche Barraclough Ltd. eroche@barracloughltd.com
