Metadata shows on website

This metadata is called “Exif”; there are plugins that can remove it on upload — see https://www.google.com/search?q=site%3Ahttps%3A%2F%2Fwww.remarpro.com%2Fplugins+exif

Hiding it on already uploaded images is a theme question.

Superba is a commercial theme. You’ll find support here:

https://themeforest.net/item/superba-mediacentric-photography-wordpress-theme/10006441/support

Forum volunteers are also not given access to commercial products, so they would not know why your commercial theme or plugin is not working properly. This is one other reason why volunteers forward you to the commercial product’s vendors. The vendors are responsible for supporting their commercial product.

Thank you for your reply.
I couldn’t find any useful plugin in the link.
I was hoping there is some kind of css code I could use for this purpose.
Before presenting the question here I already contacted the the theme support and this was their answer:

you can hide these elements by using CSS, for example the class for the exif is .thb-gallery-details-exif-taken-on.
We hope we’ve pointed you in the right direction here; as per our Support Policy, support is intended for theme-related bug fixes only and we don’t offer guidance about 3rd party plugins errors or theme customisations.

well, that’s one heck of a helpful response. ??

Please post a link to where you see this issue.

if you press any of the photos in the gallery and then press the i on the right you will see the info presented

If your theme has a “custom CSS” option, use it. If not, install the plugin “simple custom CSS”.

This is the CSS you need to add:

.thb-gallery-details-trigger {
   display:none;
}

Because you’re using a commercial theme, we really cannot provide support here.

Im afraid I don’t know where the custom css would be.
where do I need to add the code
Do I need to have child theme in order to do so?
can it mess up my website if i don’t do it right?

and I’m quite confused to what a commercial theme is and why the fact that I paid for a theme means i cannot get the support?

Thank you for your help.

Im afraid I don’t know where the custom css would be.

Install the plugin “simple custom CSS” and use that to add the CSS.

Since that is a theme or plugin, we ask that you please go to their official support channel, so you can get support from the people who know it best. When you bought the theme, you also paid for support.

Forum volunteers are also not given access to commercial products, so they would not know why it is not working properly. Other community members who may have faced your issue might be able to help you but your best bet is your product’s developer. Keep in mind we encourage you to use the official support venues, as it allows the developers to be aware of issues with their code and gives back to the community in a more robust way.

Thank you
