I updated my multisite network to Domain Mapping 22.214.171.124 today and now I'm getting redirect errors on the front end of the site while being logged in. If I view my site in another browser (not logged in) it loads fine. If I clear my cookies for my site, I'm able to reload my site. But if I log in again, then I get the same error on the front end of the site. Another result of this problem can be seen in the WordPress theme customizer. The controls will load, but the live preview won't.
Any ideas how I can go about fixing this? I have a backup, and I can restore. But, that still doesn't really fix my issue because I need to be able to update at some point.
Please advise. Thanks
