Error code.

Hi Hugo,

This is a theme issue which is seen a lot. See https://pippinsplugins.com/use-the_title-and-the_title_attribute-correctly/.

the_title() function should not be used in a HTML element attribute. This will cause broken HTML markup. the_title_attribute() function should be used instead.

Here’s an example of incorrect code usage of the_title() function:
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">My title</a>

Using the auto placement settings to display the rating results would result in broken HTML like this:
4.35/5(3)">My title

Correct usage is to use the_title_attribute() function instead for output of a HTML element attribute:
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>">My title</a>

I hope this makes sense.

Thanks,
Daniel.
