Hello,

I can't guess, can you please check the errors in console (right click on image place and inspect element to open the dev tools then click the console tab and take screenshot) on shop page.

Here it is

403 :( Please check with your server admin/host.

I am the administrator, but I don't know what to do. I have little knowledge with websites

I found the problem.
When I upload an image of a product, in the directory it has permission 604, and the correct permission is 755. How can I configure it to upload it with permission 755?

I am not server admin but the following permission should be fine
```
Directories/Folders: 755 & Files: 644
```

You might be to pay attention on the file/folder owner. Thank you

So this is exactly the problem, or our server can set permission to 755, but who knows what permission the script file is, you know?

As I told you before my knowledge of server administration is almost 0 and google found this for me [Linux / UNIX: Change File Permissions Recursively ( conditional )](https://www.cyberciti.biz/faq/howto-apply-conditional-recursive-chmod-file-permissions/) and this Questions [How do I change permissions for a folder and all of its subfolders and files in one step in Linux?](https://stackoverflow.com/questions/3740152/how-do-i-change-permissions-for-a-folder-and-all-of-its-subfolders-and-files-in)

I use shared hosting, have you tested before?

Majority of customers are on shared hosting. cPanel has option to change permissions and other hosting panel should have those option too. You can check with your host as they can guide in details.
