See UPDATE below
If you are in OneSearch about to click a “View Online” button or if you are in some database and have clicked a “Find it!” button (both “View Online” in OneSearch and “Find it!” buttons are powered by our SFX service) and get a link to full text that goes to an EBSCOhost database, odds are that link will fail. You’ll get an error message from “EBSCO Publishing” that says “A System Problem has Occurred” and looks like this:
Ex Libris, the company that provides the SFX service, says that EBSCO changed some settings unexpectedly. Once Ex Libris can update their systems to work with EBSCO, SFX should be working again with EBSCO content. It’s not clear how long this will take (hours? a day?)
In the meanwhile, as a workaround, use the “Journals” search option on the yellow search bar to track down the database that has that periodical you need. Links from there into EBSCO and other databases are fine (the “Journals” system is from Serials Solutions and is unaffected by this problem).
UPDATE (9 March 2016, 10:15 am)
Ex Libris and EBSCOhost have fixed this problem.
