DOKU renderer in TC Wiki ??

[PDP-8]

When perusing the TinyCore Wiki, some pages bother the Fifth browser with error messages writing over it's contents.  Other browsers don't complain.

I like to "eat my own dog food" so to speak by using the fifth browser to study Tinycore online docs, rather than use other browsers.  but that's me.

The errors that commonly show up have to do with "Doku Renderer" strict standards, and "cannot modify header" warnings.

Strangely, it seems random.

Is this just a wiki-thing, like someone editing the wiki page while I'm trying to browse it?
