No, unfortunately, we do not, we only offer script installation. You should always contact the writer of the faulty script if you are having issues.
This does not apply to WordPress which we will support fully, however, if it is a third party plugin causing your site issues you will again have to seek support from the person who wrote the plugin. We CAN do that for you but you would, of course, be billed for our time.
If we install any other script for you that you have purchased, it will be installed as instructed by the authors.
If you get no joy from the script writers we can have our PHP programmers look at it for you, however, that will involve you paying their usual hourly rate.
If you need help with a script you can contact us by submitting a ticket.
