Problem updating page speed pro theme

Hi, i had a problem updating page speed pro theme from 1.52 to 1.60: can u help me? TKS

What is the problem? Is an update not visible in your dashboard?

when i try the upgrade there is always an error and I’m still remain with the 1.52 version

Wordpress suggests to update the theme to 1.60, but https://members.swiftthemes.com/softsale/license says the latest version is 1.52.

Hi, we don’t always upload minor updates to the member’s area since you can update the theme later.
Here is the changelog.
