Hi there, @1231 4622 2309 589.
Thanks for posting in the Community. I've tried checking if there's an ongoing issue about opening the Manage users page. However, there is no reported investigation at this time.
It could be that your browser's cache data is full or corrupted. In most cases, this causes issues such as partially loaded web pages or not being able to open a certain page. We can use your browser's private browsing mode to root out any cache-related issues.
Here's how:
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Internet Explorer: Ctrl + Shift + P
- Safari: Command + Shift + N
If the navigation menus work using the private browsing mode, you can clear your browser's cache storage data to resolve this. Another way is to use a different browser.
Keep me updated how it goes. I'll be on the lookout for your reply and help you further if the issue persists.
