Hello. When I run otree devserver in powershell, I get the following error: TemplateSyntaxError: All content must be inside a block tag (line 1, in "<html>"). A similar problem has been handled by removing BOM from the file (https://groups.google.com/g/otree/c/z9cDSZgD7ME). In the encoding settings, I have selected UTF-8 with NO BOM. However, the error still persists. How should I proceed? Thanks!
