I've been having problems with a new install of CiviCRM 5.3 in Multisite on Wordpress.
It seems to be working properly in the main site.
My intent is to have one CiviCRM database that works across all the subsites, sharing the contact data.
On the subsites, when I go to the CiviCRM dashboard, I get the dreaded Network Error pop up. IN the Web Developer console it shows this error:
Access to Font at 'https://dev.domain.nz/wp-content/plugins/civicrm/civicrm/bower_components/font-awesome/fonts/fontawesome-webfont.woff2?v=4.7.0' from origin 'https://crew.dev.domain.nz' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://crew.dev.domain.nz' is therefore not allowed access.
And the default and the Activities dashlets just spin with the CiviCRM logos.
If I remove those dashlets from the dashboard, then the problem goes away.
I would of course like to keep them.
I have added
Header set Access-Control-Allow-Origin "*"
to my .htaccess file for Wordpress. This did not help.
I'm sure that this isn't 100% a CiviCRM problem, but I'm not sure where else to ask...
