Maybe this is not important but i think you can fix soon. 
See image:
Because i can not post more than 2 links so temporary call “coreui.io” is “{your site}”
- Demo of free templates (3.4.0 and 3.4.0/rtl)
“docs” link is wrong (almost controls)
- Sample: {your site}/demo/free/3.4.0/buttons/buttons.html
- Your REAL link of docs is
{your site}/docs/components/bootstrap/dropdowns/ - But docs link to
{your site}/docs/components/bootstrap-dropdowns/
- Docs link breadcrumb
- Sample: {your site}/docs/components/bootstrap/button-group/
- Home links to {your site}/3.2/ does not exist.
- Bootstrap links to {your site}/docs/3.2/bootstrap does not exist.
