theme has no such notice, deactivate plugins one by one

HI,

I importedthe Re:Direct demo.

The first time, it did not import correctly. So a message appeared with a red line saying ''Something went wrong. Please try again later''. (see screenshot).

But then after that, it did import correctly.

The problem is, the red warning won't go away.

Am I still being warned about something?

I have refreshed the site and cleared the cache but the red warning remains.

Do I need to worry about anything?
TY
Sim
