I am trying to troubleshoot a friend's blog, Umamimart. Everything is working great with the exception of a single author page of one author. It appears that when retrieving her information it draws a blank and thus returns posts without authors.
The author page works for all other authors. Her posts themselves are fine as well. It is only her author page which doesn't work.
I have checked the users table in the database and her row is perfectly fine. I have looked into author.php, author-template.php and myriad other files and I can't seem to the problem. For the record, there is only the author.php and no custom or specific author page templates.
I am mystified and any help or pointers would be greatly appreciated. Thank you in advance!
