Hi Wendy, Kate contacted me by Private Message as well. There may be more of a problem than cache or refresh, though I hope I'm wrong.
Kate uploaded the gedcom file on Aug 7th and less than 2 hours later, she was able to ADD names to WikiTree, not just Edit existing Profiles, Add. I found that a bit strange considering the size of her gedcom file, especially as she had Suggested Matches, and asked her some further questions.
I don't have the rights to see her file as you do and am just going by Kate's Contribution List. Am I reading her list incorrectly? See what you think.
