Same error on several different devices around here. Somebody broke Amibay. 
Somebody installed a encrypted script, but did not install the Ioncube loaders in order to decrypt the script. So they need to either remove the script or install the Ioncube loaders. Should take a few minutes only.
Or maybe they tried to do a php 7 upgrade, which needs a lot of new stuff besides the Ioncube loaders. I sure hope they didn't and hope they'll fix it soon (or get in contact with someone who knows how to fix it).
