PHP Fatal error

[Vaddalapam]

Good evening, i installed the Purchase without account module, usually i did something wrong like i always do . It did not work, so i deleted folder and files. What turned front and backend into a white page. I uploaded a backup from yesterday morning via ftp, and i can't explain, the white page is still there. Can anybody tell me what following lines mean to me ? I'll be a beginner for a long long time.

It’s because you didn’t uninstall the PWA modules before deleting the files, so the configuration entries are still in the database configuration table.
Upload all PWA files again, uninstall all PWA modules, specifically the customer data guest module. Then you can delete again all PWA files.
Note that support for Addons is given where you downloaded the addon in the support tab.
However PWA should work. You may post there what exact didn’t work and you would get support.

I followed raiwa's instructions, the addon works like it should. No more white page. I don't know what i did wrong when trying the first time. Problem solved. Thank you for helping
