Import-Error

What does tell me this error exactly, which i get since today, without have done any changes on my editor?

Might be a system glitch. Bugs and system issues should be reported to Wix Customer Care to ensure timely handling of your issues.

Will be done, if i can’t figure it out the next few hours xD, thanks Yisrael.
I already assumed that it must be a wix-sided …


…but want to be sure, it is not caused by my own coding.
