Thank you for contacting VolThemes today.
A common issue that can occur to installing WordPress themes is a “Broken theme and/or stylesheets missing” error message being displayed when trying to upload or activate the theme. This error means it has been uploaded incorrectly.
First, you need to unzip/extract the file ‘lycka-package-1.0.4-unzipme.zip’.
Once you unzip the file, make sure to upload
lycka.zip through your WordPress admin section.
– Go to ‘Appearance > Themes’ section
– Click ‘Add New’ and select the ‘Upload Theme’ option
– Choose the
lycka.zip file and press ‘Install Now.
– After uploading the theme, you must activate it. Navigate to the Appearance > Themes page to activate the lycka theme.
That’s it! You’re all set and ready to go 🙂
