Updated WP and network to 3.6 from 3.5.2 on 8/5/13. Update worked fine, but subdomain site disappeared - returned a blank white page when I went to site. Same blank page for site dashboard.
I reloaded Bluehost daily backup to WP 3.5.2 and site is fine.
Does the 3.6 upgrade require resetting the wp-config multisite flag?
/** Enable or disable Worpress Multi-site features **/
Do I have to rebuild the htaccess file again>
I setup WP multisite in 2/2013 and it has worked fine with wp3.5.1 and I migrated to 3.5.2 with no issues.
Is 3.6 undoing multisite changes in wpconfig and htaccess that I have to redo by hand after update to get multisite to work again, or should the installer check that it is a multisite and not be changing things?
