So if you call ##example.com## the installer is called again, but when you call ##example.com/HomePage## it shows you the wiki.

How you managed to do that?
The installer is only called if there is a empty **config.php** or when the ##WACKO_VERSION## in the **constant.php** is bigger than the corresponding ##wacko_version## in the config file.

I'm not sure what may cause this.

Please remove the **setup/** folder from your server. 
Delete via admincache action the page and config cache.
Check ##example.com## again.

From the header above  it look like a non WackoWiki related cache issue to me.

Please check your hosting environment. I'm not familiar with cloudflare services, see ##cf-cache-status: HIT##.
