In my admin, my catalog configuration page is completely blank. I have not edited any of the code for this page. I do have a custom frontend theme installed, however.

I have already flushed set the caches under System > Cache Management, reset browser cache, and checked the admin page in question in another browser.

I am using Magento 2.2.1.

  • Looks like an issue with one of the system.xml files in your instance most likley a 3rd party extension / theme i would recommend disabling all extensions and enabling 1 by one to determain which one is causing the issue or to save time you could edit the app/bootstrap.php and find #ini_set('display_errors', 1); and remove the # save and upload this should then display the errors on the page making easier to debug – Dava Gordon Aug 30 '19 at 07:35

I would try:

php bin/magento maintenance:enable

delete everything in the var folder except .htaccess

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento cache:clean
php bin/magento cache:flush
php bin/magento setup:di:compile
php bin/magento maintenance:disable
php bin/magento index:reindex

the solution is 

chmod -R 777 /path/xxx.com/public_html/generated/code/Magento/Catalog

how to find solution is

first,go to see /var/log/system.log ,you will see something about "main.CRITICAL: Can't create directory",which means permission problem.
