plugin manager update broke admin
Asked by gord:

hey all, I updated the plugin manager today (though I didn't track versions, sorry), and now my admin access is... well, gone. just goes to a blank page. non-admin stuff seems fine still. Any suggestions?

It's likely you're on universal plugin manager 3.0.6 or 4.0.7 (depending on your Confluence version). Let's try a few things to see if we can get you back in business!

* First, **has Confluence been restarted** since the plugin manager was updated? If not, let's start there. Even if the problem persists after a Confluence restart, there will be a clear marker in your application logs to work from.
* What **version** of Confluence are you running?
* After restart, do you see errors in the **application log** after you try to load the admin pages? Can you paste the output of those logs here? [See here for info](https://confluence.atlassian.com/doc/working-with-confluence-logs-108364721.html) if you're unsure about where the application logs are.

Thanks!

I believe it was on 3.06 prior to me hitting update... it has been restarted, no change to the admin side. Running 6.15.4 on Ubuntu 18.04.2 LTS.

Event logs - I assume you speak of the Windows ones had it been installed there, and assuming that the same logs exist on the Linux side (though I don't know where to look). if you can point me the right way, i'd appreciate it!


author: Daniel Eads
body: The application logs are in **\<confluence-home\>/logs/atlassian-confluence.log**- if you went with the installer defaults in Ubuntu, that path is likely:

```
/opt/atlassian/confluence-home/logs/atlassian-confluence.log
```

Otherwise if you still don't see the confluence home directory (this is separate from the installation directory), you can find the path to it from this file in your installation:

```
<confluence-installation>/confluence/WEB-INF/classes/confluence-init.properties
```

And if the installation path is even a mystery, running **ps aux \| grep confluence** should print Confluence's running process, which includes a lot of pointers to the installation directory.

I tailed the last 200 lines of the log itself, there were a few warnings, but nothing that stands out.

body: hey guys, after a busy couple of weeks, I think I need to get back to this. As I mentioned in my last note, there was nothing interesting in the logs. Admin is still broken though.


author: Daniel Eads
body: Hey [@gord](/t5/user/viewprofilepage/user-id/3580963) - here's an action to try and how we go from there:

The plugin manager is a plugin itself. It's possible that there is some conflicting code trying to load. I'd expect Confluence to just not render content in this instance, but let's try clearing the plugin cache to see if that changes the situation. [You can follow the instructions in this article to flush the plugin cache](https://confluence.atlassian.com/confkb/how-to-clear-confluence-plugins-cache-297664846.html).

If the problem persists after that, we'll need more information to hone in on the problem.

1. Can you provide a screenshot of the blank page you're seeing (including URL)? Does the "Inspect Source" for the page provide any content at all?
2. You noted there was nothing that seemed interesting to you in the application logs. Would you be comfortable posting them? While you might not find something particularly interesting, it's possible there are lines in the log file that lead us to a cause.

Thanks!

Daniel
