Working with elementor

Hey,
I was working with wordpress, for a while now , but still i am very new and i am not from a IT background.
I have encountered a problem related to saving the work, as when i am doing the work with elementor page builder the work which is shown in the preview was not been able to save, so when i have been opening the website the work is not shown.
Can you please look into the issue !!

Thanks and Regards
