I have recently installed Magento 2.3.5-p1/2.3.4 with sample data (different versions to solve this problem) and everything seems to work fine in frontend or admin panel. However, if I try to create new customer, or new product, or view current pages I have, or themes option in admin panel I get a blank page.
1. Admin > Content > Pages
.
2. Admin > Catalog > Products
3. Admin > Catalog > Categories
I don’t have any errors in Nginx logs, however I see following type of errors in system.log
which I believe should be ignored as thats what I found on the internet.
[2020-07-13 05:52:54] main.INFO: Broken reference: the
‘product.reviews’ element cannot be added as child to ‘product_tabs’,
because the latter doesn’t exist [] []
I have already for help on several other forums but none was able to help, so I am finally posting here. I hope someone can guide me.
UPDATE:
Affected page are:
Admin > Customers > All Customers > Add New Customer
Admin > Catalog > Product
Admin > Catalog > Categories
Admin > Content > Themes
Admin > Content > Configuration
Admin > Content > Pages
Admin > Content > Blocks
Not Affected in these tabs:
Admin > Content > Schedule
Admin > Content > Widgets

the problem was with ngx_pagespeed module, I disabled Page Speed and now it works absolutely fine without any errors.
I added following line to nginx configuration file.
Can you enable php display errors in index.php
Simply the code below to the top of index.php and create products or pages
