Some Admin Controller Pages Gives White Pages 1.7.6.4

[burakpresta3]

Hvello, 

i hope someone will give me a good answer to fix this, because i am really really sad about this. 

Problem AT BACKOFFICE

I move 1.7.6.4 localhost to LIVE. Also i update it without any problem, it is also working under localhost.  First i tried bakwire order, no problem. Then i try to change order status, it gives blank white page, every time but it changes the status without problem. Notice that it is realted with 

under controller/admin/adminorderscontroller.php

line 562

Tools::redirectAdmin(self::$currentIndex . '&id_order=' . (int) $order->id . '&vieworder&token=' . $this->token); 

if i delete this line, it is refreshing the page without  stuck.. 

After this, i tried some other bakoffice SAVE buttons, same situtation again.. Most of them is related with admin related things,

• -  index.php?controller=AdminOrders&vieworder=&id_order=5213&token=d11e478b2dd6bb49d1f2d8116dfe021a
• -  contoller=AdminAddresses
• contoller=admincartrules
• controller=adminmodules
• controller =adminpdf

do they have common things ? i can easy local to live to fix it, but i dont have any hope. 

if it related with "admin", it gives White Screen.  Will you please read this link, it is detailed problem. https://github.com/PrestaShop/PrestaShop/issues/18710 with images.. i couldunt find any solution.. This is commercial website, and it is not working well.. it is is simple stuck problem, but where. 

what i did WHAT we have 

- cleared cached, var/cache, cleraed theme cache, debug mode, php version 7.2, mysql is ok, no php log, no server log, it is like ajax stucking suddenly if i refresh page, most of time no problem with warning like " allready assign", sometimes, if i back, it is saved no problem.. 

For example sliding module, shows a blank white page but it saved the image for slider. 

 

I have fixed lots of things by using this forum, but i am in stuck right now. Please TELL your ideas, i will try.
