I had the same problem as described by the OP, and I’ve just solved it with the corrected code mentioned above by tormenta234:
add_action(‘admin_head’, ‘theme_fix’);
function theme_fix() {
echo ‘<style>
.form-table span {
width: auto !important;}
input {display: block !important;}
</style>’;}
I’ve inserted this code in the functions.php file just below <?php.
It all works fine now. Thanks!
