Prestashop 1.7.6.2 Blank Page on edit Product Back Office

[skylabKevin]

Hi Everyone,

 

I have a serious problem, whenever i want to create / edit product, i got a blank page on PROD (no errors in prestashop logs, php logs and apache logs) , if i switch to debug mode, the product page shows without no errors.

I've already :

• Clear cache (/var/cache/dev & /var/cache/prod)
• Rebuild .htaccess

It happen somewhere around the formAction in ProductController.php (i can do a die('ok') within this method and have my 'ok' displayed before the return (method formAction))

 

Thanks for your help
