HI.
Here is the instruction. Our plugin supports WordPress standard translations, so you should translate the plugin by using the Poedit program.
You will use the Italian, so you need to change it from our plugin translation files. Go to FTP and find our plugin folder, then open the booking-calendar\languages\ folder and find this file – booking-calendar-it_IT.po. Then download it to your PC.
After that download Poedit(https://poedit.net) program and open this file with Poedit.
Then find words you need to translate (once you open the program, you can press Ctrl+f and type there “Sunday” and then press enter, and the program will search and find that word) and change or add translations for those words (if you click on any word, you will see “Source text:” and “Translation:” in the bottom, type the Italian word in “Translation:”).
Then click on the Save button. After this, the Poedit program will automatically create a booking-calendar-it_IT.mo (in the same folder on your PC where the booking-calendar-it_IT.po file is located) file and update the booking-calendar-it_IT.po file. Upload (replace) booking-calendar-it_IT.po and booking-calendar-it_IT.mo files in our plugin languages folder (from FTP).
After this make sure that the “Use mo” option from our plugin admin panel is selected (Booking Calendar>Themes>Default texts>”Use mo” on the top side).
That’s all, now our plugin will translate the Italian words if you have selected the Italian language for your WordPress website.
As for the “not to display the availability and prices of past days” feature, it is a premium feature located on the Calendar Theme page > General Settings tab > “Delete previous dates”.
Thank you.
