Getting Page Error for Admin Settings Page

[lego_admin]

Hi All,

For the canvas instance we are using we are getting the following error when we click on Settings in Admin Accounts 

"

Page Error

Well, it looks like something broke unexpectedly. Sorry you had to see that. If you have a second, please let us know what you were doing when the error happened."

Can someone please help on this

Hi  @lego_admin ,

May I ask, are you using a self-hosted instance of Canvas or the Canvas application hosted by Instructure. Dependent upon your answer, I can aim to point you in the right direction.

Look forward to hearing from you.

Cheers,
Stuart

Hi @stuart ryan ,

We are using self hosted instance. In that case what would be the solution for my issue.

Thanks

 @stuart_ryan ‌Canvas Developers,

Will you be able to provide an answer for my issue.

Thank you

Hi  @lego_admin ,

Apologies for the delay I have had a busy few days. The Canvas Community is a place where community members like you and I can help each other out, hence it may take a little time to get a response.

I will admit I have not completed an install of the self-hosted version before. However, I can point you in a few directions. Can you please advise if you have looked at your web server logs and if there are any details that appear in the log (specifically errors) when you try to access that page? I would recommend ensuring no other users utilise the system at the time you capture the logs, as that will minimise noise and hopefully enable you to narrow things down further.

I would also then recommend checking your Canvas logs which, if you followed the installation instructions at Production Start · instructure/canvas-lms Wiki · GitHub , will be located at /var/canvas.

Can you please have a look in these logs and see if there are any messages that are generated at the time when you try to access the page.

If nothing shows up in either of those, you may also want to check the PostgreSQL logs to see if any database errors have occurred, if that *does* happen, I would anticipate a reciprocal log would be generated in the Canvas logs too.

Please let me know how you go with this and if there are any errors that you see in the logs. I anticipate the most likely place will be in the Canvas logs, but it never hurts to check the web server logs as well.

Cheers,
Stuart

 @stuart_ryan ‌ Thanks Ryan. We will check on this

I am having the same issue. Were you able to figure out what the problem was and a possible fix for it? 

[featherstonej]

 @stuart_ryan ‌ I have looked through the logs and I found an error in the error log table in the database, but I am not sure exactly what is causing the error. I know I had changed some of the Two-Factor Authentication settings just before it started happening, but since I can't get back to the Settings page I can't undo what I did. Is there a way to change the settings either in a config file or in the database?

[stuart_ryan]

Hi  @featherstonej ,

There would be a way to undo this through either a configuration or database setting, however, unfortunately that goes far beyond my experience. At a general level I would suggest looking for a configuration or settings table and then familiarising yourself with that. If you have a backup of the database you could spin up alongside you could potentially do some comparisons from before and after you made the settings change and that may help point you in the right direction also.

Apologies that I can't be of more assistance.

Cheers,
Stuart
