Sorry, I'm absolutely new to Joomla! And with the templates, and I have the same problem.
Before making the changes on the server web, I made the update in the Localhost of my computer and there was an error when installing the template. Still the template appears as v. 3.22. (Attached screenshot)
Can you tell me the steps that I have to do to carry out the update? Or where it is possible to look at them
Thank you.
