Issue with studio to custom layout

Hello, I have installed on my site SuiteCRM with Softaculous.
I want to configure the fields in the contact and leads sections for my business. But when I use Studio, I modify the edit view, save and deploy, but nothing changes in the CRM. I tried to clear the cache, and even change computer to check but nothing works. Could you please help me?

It could be an issue of file permission. Make sure you have correct file permission as per this
