Does the convert to Bootstrap 4 do the entire site or do you have to manually convert each and every page?

Hello Brad,
The conversion is per page, as bootstrap and app connect are included per page.

I have discovered that if you have used one of the Bootswatch themes the conversion is really bad. It doesn't keep the Bootswatch theme obviously as the theme is still in the Bootstrap 3 folder.

So only use the converter if you have used an un altered Bootstrap 3 style.
