Admin unable to log in as other users when 'allowAdminChanges' => false

[johnfmorton]

Description

The title says it all.

Admin-level users are unable to log in as other users when 'allowAdminChanges' => false.

In 3.1.5 I was logging in as my other users and tweaking their account widgets but now that I'm in 3.1.6.1 I can no longer set up these accounts.

I receive this error dialog box:

Steps to reproduce

1. 'allowAdminChanges' => false in config/general.php
2. Log in as admin
3. Attempt to log in as a lower level user (aka an "Editor" type of user)

Additional info

• Craft version: 3.1.6.1
• PHP version: 7.3
• Database driver & version: MySQL 5.5
• Plugins & versions: Guest Entries

Thanks for reporting that, it’s fixed for the next release!

To patch your install and get the fix early, change your craftcms/cms requirement in composer.json to:

"require": {
  "craftcms/cms": "dev-develop#0cf5513a84020b927b1e5534e9c98cab950ccbf8 as 3.1.6.1",
  "...": "..."
}

Then run composer update.
