Could you please provide information on which theme you are using? Also, if possible, please send a link to your website and we will check it in more detail.
I am using the Rentalhive theme. Everything was working normally before the update.
I deactivated the “Enable gallery preview” because I could not let the website remain like this, so there is no point to check the website now. With the option deactivated, it looks all normal.
I tried deactivating another plugin (EWWW Image optimizer) because of a possible conflict but it has no effect.
This feature is still in beta, so we need to release an update for paid themes. For now, we recommend disabling it, and once we fix it, you can enable it.
