When I click on Configuration Information in my Prestashop 1.6 back-end admin panel it takes a long time to load and then I get a white browser window with nothing in it.
Hello,
Thank you for contacting us about a White Screen in PrestaShop. When you see a white screen, it is typically suppressing an error message. Enabling Error Reporting in PrestaShop will cause the errors to display, instead of a white screen.
Often, the error will list a PHP setting in the message, you can then adjust your PHP settings as needed.
If you have any further questions, feel free to post them below.
Thank you,
John-Paul B
