* Hello,
* Thanks for your message. We suggest getting in touch with our team through our
website for questions related to the Pro/commercial version of the plugin. Options/
extra services are not available in the free version of the plugin, and so in
order to not go off-topic on this forum, we suggest getting in touch with us
through our website or by opening a support ticket. Thank you!
* The error with code 403 (Forbidden) is probably caused by a third-party plugin,
or by some security rules in place on your server. That error message has got
nothing to do with VikRentCar, it’s usually a firewall rule or a security plugin
that intercepts requests containing PHP code.
* Also, Options/Extras can be configured as “mandatory”, by turning on the parameter“
Always selected”. You may not need to modify the PHP code, and if you needed
to do so, then editing a PHP core file is strongly discouraged, or you will lose
your changes by installing the next official plugin update. It would be even
worse if you decided to keep an old version for a customization that was not
done properly. In fact, the step #3 of the booking process is a “View” (page)
that can be overridden. Thanks to the overrides technique, you will be able to
work on a cloned copy of the original template file of a specific “View” of the
plugin.
Overrides can be created manually by following the technical documentation
on our website, or you can just use the “Overrides Manager” tool available in
the Configuration page of VikRentCar.
* This way you will not apply any changes to core files, and you will always be
able to install future updates without losing your customization.
* We hope this helps!

* Fyi i have the pro version. 403 caused from my firewall settings you were right.
Thats i want to change is the option to be selected but not mandatory, user can
unselected if needed, but when enters the step 3 for marketing reasons I want
to be already selected(checked). I make a change in the showprc default.php file
via the in the input to be checked in the VikRentCar – Page Override but nothing
happened.

* Also for some reason even with changes or reverted to the old php file the icon
now is red.

* Hello,
* Thanks for sharing the details. We are glad to see you’re using the “Overrides
Manager” tool so that you are actually working on a non-core file, but rather
on a copy of the default template for the View (page) that shows the options/
extra services during the booking process.
* What we can tell you is that the “red icon” in the Overrides Manager means that
your override is disabled (inactive). By clicking the gear icon next to the file
path at the top of the main editor window, you will be able to activate the override
again. You need to select that file with the red icon first. The file-icon needs
to be green for the override to be active.
* Also, we confirm you’re working on the correct file and adding the `checked="
checked"` attribute to the input tag is the right solution. We understand you
don’t want the options to be mandatory, but rather selected by default.
* Just make sure your override is active, and you can add some additional code
to make sure your override is working, even something like `echo 'we are here';`
will help you understand what portion of code you’re working on.
* We hope this helps!
* The VikWP Team
