Starting on March 26th, a small subset of Wordpress sites were placed in read-only mode as part of the migration of all sites from Armor Hosting to Azure. Those sites which have not yet been migrated have been placed in read-only mode. While in read-only mode, constituents will be able to navigate to your site and donate without error, but you will not be able to login to the site while it is in read-only mode. If you encounter this issue, please chat with support or email to schedule your migration.
