I have purchased a theme for wordpress on ThemeForest, when i upload the .zip have a error with wordpress.
Are you using wordpress.com possibly? You cannot install themes to wordpress.com only self hosted wordpress.org software.
“missing stylesheet” error by any chance? Make sure you are uploading the THEME folder NOT the entire download from here
Unzip it and search for docs there, it should have some instructions how and which file to install.
I’m uploading the correct file, now i try upload with the host panel. Stay, keep.
