Stylesheet only applying when logged in

Well, that’s odd. My first guess would have been caching, but it sounds like you’ve pretty well explored that avenue.

Does the stylesheet appear for *any* logged in user, or is it just appearing for admin users or for yourself?

There are a number of checks to verify whether the CSS should be loaded or not, but none of those checks are user-based. However, it’s not impossible that a plugin or theme could change something depending on user log-in that could have an impact – I’m just not sure what it would be.

Have you limited the CSS usage in the plugin settings? E.g., added a value to the ‘Load CSS only on selected pages’ option?

Hello Joe,
Thank you for your reply, I figured out the problem with your help. I turned off every single plugin again to check for change in behaviour and this time I spotted a change when the plugin “asset cleanup” was turned off. That made it a lot easier to investigate. It turns out that the sitewide unload setting “turn off dashicons when admin bar is hidden” also blocks the calendar stylesheet for every logged in and off user except the admin. After unchecking the calendar works for every visitor.

kind regards

Thanks for following up! That’s useful to know.
