Hey @Yair_Hazan!
Have you got more info about what you’re experiencing? e.g. a screenshot of the error, the site it’s happening on, any code being used and the steps to reproduce.
If it’s not working in preview and you don’t want to publish to the live site, there is the option of using a test site (more details here), that is closer to the live environment without being live.
Also adding @StudioSpecialist’s if they have any insights
