Thanks @codeamp!
Keryn’s fix worked for us too. I’m new to this forum and might have found that previous post myself if I’d looked a little harder. I would like to give you the debug output you’ve requested, but it isn’t easy for me to enable WP_DEBUG or to get at the output on this particular site, and I’m afraid it may not be throwing errors now that everything is working. If I can get that output for you I will post here.
