App Page Not Loading Properly

Nextcloud version ( 15.0.7):
Operating system and version (CentOS 6):
Apache or nginx version (Apache 2.2.15):
PHP version (7.1.26):

The issue I’m facing:
The app store page is not loading properly. The section below “Developer documentation” is not loading at all. Other section is working fine.

As a result I’m not being able to add new apps in the system.

Steps to replicate it:

  1. Login as admin user
  2. Go to the +Apps menu
  3. Section below “Developer Documentation” not loading

The output of your Nextcloud log in Admin > Logging:
