Upgraded and now the store front shows blank screen

Hello, I upgraded the opencart store to the latest version and now the admin area works, but when trying to access the store it just shows a white screen. It said that the upgrade had been successful. Has anyone else had this? How can i resolve this issue?
Thanks

This is a handy article to debug your blank screen. Could be a number of issues. Most of the time it involves a custom theme. Always a good idea to switch to default theme as a first test: https://multimerch.com/blog/blank-pages ... on-causes/

Also make sure the folder paths are correct in config.php

thank you Avvici I will have a look at the article and check the theme :-)
