Squarespace Email Campaigns page blank in any browser
Hi everyone,
I am a software developer who has been working with Squarespace to resolve an issue with their new Email Campaigns offering. However, we believe this may be controlled by something on macOS. This is a complex issue so please bare with me.
Task: Login to Squarespace, click Marketing, click Email Campaigns.
Expected result: Loads the Email Campaigns dashboard.
Actual result: Page goes blank.
Some notes:
1) This issue only occurs on my default local user. If I make a new user in macOS, it works as expected.
2) This issue originally only occurred in Safari 12.1 (14607.1.40.1.4). After a week, it now occurs in Chrome (74.0.3729.157) and Firefox (66.0.5).
3) I have tried clearing local dns cache, local browser cache, disabling startup items, disabling addons.
It's almost like there is some security, tracking, or safety setting on my default local user. Or something was cached on Chrome for a week that was refreshed on Safari.
Any insight?
