Hello all, First time poster here. I've been playing around with ProcessWire for some time and am currently in the middle of my first project based entirely on PW. I have a problem with the field type drop-down list in the "Add new field" tab. All of the sudden it's blank. Am I missing something, or is this an error? It looks like this, no field types, nothing. I didn't even modify any particular settings in the meantime. Half an hour ago it was working just fine. Thanks in advance for any help.
