The package hyperref has already been loaded with options:
  [hidelinks]
There has now been an attempt to load it with options
  [unicode]
Adding the global options:
  hidelinks,unicode
to your \documentclass declaration may fix this.
Try typing  <return>  to proceed.

when i try to convert to pdf, i get an empty html file.

Answer 1

The moderncv class automatically loads the hyperref package. You can use \PassOptionsToPackage{hidelinks}{hyperref} to make sure it is loaded with the options you want.

(although your hidelinks option won't make a big difference because moderncv sets the line width of the link boxes to zero, so they are already invisible)

\PassOptionsToPackage{hidelinks}{hyperref}
