Avoid empty "href" attributes

Hi

I really like your plugin, but when testing my site with dareboost, the following error occured:

Avoid empty “href” attributes

The “src” and “href” attributes allow to access another resource, or to another section of the page. Nothing justifies their use with empty values.

This page contains 1 empty href attributes:
?Akzeptieren

Any diea, how to avvoid this?

Cheers
Hansj?rg
