Can you clarify what you mean by the “Manager Login button”? This sounds like it may be something specific to your site rather than core-provided, unless I’m misunderstanding.
Perhaps provide a screenshot of what you’re looking at?
After you tried to login and got redirected to the frontend, is it then possible to visit other sites of the manager directly when you use an URL like https://yoursite.com/manager/?a=resource/update&id=1 or https://yoursite.com/manager/?a=system/settings?
Is the problem only the manager welcome page (https://yoursite.com/manager/)?
Go to .../manager/?a=system/dashboards and remove the widgets from the startpage.
(Especially the “Config Check” widget generates problems lately. Although I don’t know why yet.)
Are there any related PHP errors in the server error log that you could share?
I’m still trying to figure out why this widget suddenly breaks for some of the sites.
Thanks.
I was more interested in the server error log and not the MODX error log.
Other users who had problems with the “Config Check” widget reported that the “Installer” site (manager/?a=workspaces) doesn’t work correctly as well. Is that the same on your site?
If you have live access to the server log, then please share the error message that gets added to the log when you visit /manager/?a=workspaces or open the welcome page with the “Config Check” widget (if anything gets added at all).
The problem seems to be cURL related. So maybe you could search the log file to see if there are any recent messages mentioning “curl”.
