The plugin does not change the titles, it requests them from WordPress via the get_the_title() function and prints it as-is.
Do you use an advanced title field of some sort? Custom fields usually does not contain HTML tags, but often the values are rendered within the theme via custom codes.
I think I know what the issue is. In the most recent version there was a change regarding attribute escaping in the titles, which is incorrect.
I will mark this as a possible bug and change it in the upcoming release.
To resolve this, you either have to temporarily downgrade to the previous version or make a file change.
If you want to make the file change, then open up wp-content/plugins/ajax-search-lite/includes/views/result.php file on your server, then find this line:
<?php echo esc_html($r->title); ?>
…and replace it with:
<?php echo $r->title; ?>
And that will do the trick.
All the best, Ernest
