Some browsers are particularly strict about HTTP headers (Firefox more than  
Chrome) so I'd search for a recipe sending or modifying HTTP headers, or for  
a recipe/bug sending some content before PmWiki has sent all headers.

Core variables which modify HTTP headers include $EnableIMSCaching and  
$EnableDirectDownload. Recipes which can modify headers include those  
performing some caching and those sending cookies.

On my hosting plan I can enable "production" or "development" modes, the  
latter adds HTTP headers preventing the caching of a page or file, so you  
may also check this.

Other than that, apply the usual bug-hunting strategy: disable all  
customizations (simply rename config.php and create a clean clear one) then  
progressively add AuthUser, then all other recipes, and every time test the  
wiki, until you come to a state where the bug appears.

Good luck,
Petko
