I'm new to PHP and WordPress, but I have some experience with python, for my site I use the traveller theme.
How can I find the exchange rate variable that exists in theme settings (the red square on the screenshot)? I need to change it automatically with another function, not manually via theme settings.
What are possible ways to find such variable, or is there any convention where all theme variables stored?
The only closest piece of code I found is on screenshot #2 (wp-content/themes/traveler/inc/st-theme-options.php), but I'm not sure if that's what I need & how to reassign it. Thanks
