Hello,
If you want every user titles directly removed from the database, then you can go with the solution posted above, but if you only want to hide it only in your template, then just add the following code in additional.css
You can find it in Admin CP > Styles & Templates > Style Manager > {Your Template} > Edit Templates > CSS Templates > additional.css
Code:
.usertitle {
display:none !important;
}
You can apply any of these solutions.
Regards.
