Hi,
Thanks for your message. Unfortunately, for the moment there are no configuration settings available to choose the currency position, I’m sorry. This option is available in some others of our WordPress plugins, but not yet with VikRentCar.
We may add this configuration setting in the future with new updates, but for the moment the only solution is to create an override for the various pages you wish to modify and manually change the currency position via code. At least, by using the overrides, you will be working on copies of the original files. You will not lose your changes by installing future plugin updates, and you will not be editing any core files.
