Without details on what error you get nobody can help you.

Also, check your indico.log file on the server for the full error with a traceback.

You need to look for the error, around the time when you got it. None of the things you posted are likely to be related.

Before every thing was working . following things I tried.

chmod 000 to /opt/indico/.venv/lib/python3.12/site-packages/indico/modules/admin to disable access of admin . this did not work and while accessing to the website it was giving below error

Something went wrong**

internal server error (500)

I gave 750 permissions and was able to acess the website and user able to submit.

But when I am trying to change the configuration or text i am getting this.

I tried restarting all the service indico-uwsgi, nginx, celery, redis still the issue

Do you also get an error when trying to run indico shell?

If you get an Indico-themed Internal Server Error, then there should be a somewhat meaningful error message and an entry in indico.log.

If you get an unformatted error message something is broken in a way that even the built-in error handling code could not recover it, in that case also check the systemd journal log and/or output for indico-uwsgi.service.

any relation to pycache of admin folder

Not likely. Unless its permissions are messed up. Can you please start looking for the error?

Alternatively, just upgrade to 3.3.7 and see if it disappears. You need to update anyway considering that release contains security fixes. And upgrading would make sure any weird changes to the code you made and that may still be around go away for good.

Locally configured indico3.3.6

/opt/indico/.venu/lib/pythons../indico/module in this location admin folder was there. I have change permission to 000 to admin. Couldnot access the website. reverted back the changes. now below is the permission

drwxr-x—. 4 indico www-data 4096 Jun 10 15:47 admin.

I rebooted the system.

Now when i login usign admin account and try to change any thing on the conference details I am getting below entry in indico.log

Something went wrong internal server error 500 on web broswer. There is no specific entry in indico.log.

Below is nginx access log

There is no error log also.

Help

400 usually means the client sent bad data. Use your browser’s dev tool to check the HTTP resposne body.

PS: Update to 3.3.7 - you are using an outdated version w/ known security issues.

Can you please stop crossposting? One thread is enough. Especially since it all seems to be the same issue.

15

Is this possible to upgrade while live conference is going on and users are submitting the abstract

16

Yes. It’s just a few moments of downtime. See the docs on how to upgrade.
