Check if running latest update First thing to do is to make sure that you are using the latest theme update, go to theme page on theme forest and check Last update section to see if you downloaded the theme after the last update date if not then redownload the theme and update the files on your server.
Check if the bug is not present also on opencart default theme If the bug is still present after the update then make sure that is a theme bug by temporarily switching the theme to opencart default theme and check if the bug is still present after the change.
Send bug report only after checking last update and opencart default theme If the bug is not showing for opencart default theme then this is either a misconfiguration or a theme bug, you can then post a comment on theme page comments section or send me a message using the contact page on themeforest.
Detailed bug description required You will need to include the bug url and detailed steps to reproduce the bug along with opencart, php and browser version, if the bug is shown in the admin backend also temporary opencart admin access is required.
