Check your .env file. Do you define a CRAFT_ALLOW_ADMIN_CHANGES variable in there?

[AmsalSugihan]

i actually already set it on general.php settings

$config = GeneralConfig::create()
    ->timezone('Asia/Singapore')
    ->defaultWeekStartDay(1)
    ->omitScriptNameInUrls()
    ->preloadSingles()
    ->preventUserEnumeration()
    ->cpTrigger(null)
    ->headlessMode()
    ->disallowRobots()
    ->baseCpUrl(App::env('BASE_CP_URL'))
    ->aliases([
        '@webroot' => dirname(__DIR__) . '/web',
        '@primaryUrl' => App::env('PRIMARY_SITE_URL'),
        '@previewBaseUrl' => '@primaryUrl/api/preview',
    ])
    ->devMode(true)
    ->allowAdminChanges(true)
;

Right, but if you have a CRAFT_ALLOW_ADMIN_CHANGES environment variable set, that will take precedence. Did you check?

[AmsalSugihan]

Thanks @brandonkelly , when i use ->allowAdminChanges(true) i don't set the CRAFT_ALLOW_ADMIN_CHANGES on my env, but when i put the CRAFT_ALLOW_ADMIN_CHANGES , now its work.

[brandonkelly]

Try commenting out your change, and then going to Utilities → PHP Info within your control panel, and searching for CRAFT_ALLOW_ADMIN_CHANGES. Are you seeing any references to it there?

If so, then CRAFT_ALLOW_ADMIN_CHANGES is in fact getting set somewhere – just maybe not in your .env file.

I have a similar issue, but not sure if it's really related.

I've set the CRAFT_ALLOW_ADMIN_CHANGES=false to disable changes via the frontend.
When I run php craft update all --force --backup 1 --interactive 0 --minor-only it first tries to run the migrations and then aborts with the error Changes to the project config are not possible while in read-only mode. and reverts everything.

If I understand it correctly, --force should exactly prevent this. Is this behavior expected and/or is there a solution to it since my update process is automated and I don't want to edit the .env file manually?

Update: I experience the issue since Craft CMS 5.6.17 and also 4.14.15. I think before it worked without any issues.

[brandonkelly]

@ammannbe --force just gets you passed the allowUpdates config setting, if that’s disabled.

allowAdminChanges is a different beast. The update command has never made an exception for that.
