Update 2: you can close the thread, problem solved, some of the files remained not updated
Update: I managed to get some things back. Now it looks like the things not working are the Recent Portfolio and Service Icon shortcodes
I have updated the theme. Nothing changed :(
Updates between version 1.2 and 1.2.6 are missing the changed files in the Change log: https://themeforest.net/item/specular-responsive-multipurpose-business-theme/9412083#item-description__updates
I have customized the theme by modifying the theme’s php files and that is why I haven’t upgraded the theme.
Can be closed, “magically fixed”
