Common Theme Installation Problems

Are you sure you want to do this?
If you get the "Are you sure you want to do this" message when installing konstruct.zip file via WordPress, it means you have an upload file size limit. Install the theme via FTP if this happens, or ask your hosting company to increase the limit.

Missing stylesheet file
If you get an error saying that the stylesheet is missing, then you have uploaded the wrong folder. Please check that you are uploading the konstruct.zip within the Theme Files folder. You have to unzip the file that you download from Themeforest to find this.
