Administration message displayed to visitors

The message does not include any sensitive information nor is the code failing, so is this a bug?

From an automated configuration/deployment standpoint, what hook do you (and others reading this issue) prefer to trigger re-creating the snippet files? Seems like cron and flush caches are the two relevant ones.

This is definitely not correct! We shouldn't be displaying messages to visitors that are irrelevant to them.
Plus it took me a while cause I thought it was my code doing it.

It is true for D8 too.

Maybe the watchdog function is a better option.

Above commit: revise message text, restrict message display to admin users, and log error messages.

Thanks to those who reported this and commented. Please test commit and report back.

Hello, Noted this issue was first reported on the D7 branch but the patch was only applied to D8. What is required to back port this to D7 and roll out a release?

Thank you.

This was done under #2922047: Snippet file creation messages are confusing and is included in release 1.4.
