"Oops - an error has occured": Confluence not working any more. PDO Sqlite Problem (php5-sqlite)?

[Sebastian Buckpesch]

Hi,

out of a sudden my Confluence is not working any more. I already checked the DB Access Data as I found solutions for a problem in LazyReference.java:152. The DB Access is correct, so this can't be the problem. What I did is I installed the "php5-sqlite" package. After that this Error message appears, when I enter my Confluence Url.

Any proposals, what could be wrong here?

Thanks a lot,
Sebastian

Are you using SQLite for Confluence? For your information, Confluence is only compatible with MySQL, Oracle, SQL Server, PostgreSQL, and HSQLDB (this one for evaluation purposes).

If you are using SQLite for other applications, please check the atlassian-confluence.log in the Home Directory or catalina.out log in the Installation Directory for any clues regarding this.

Hi Amalia,

thanks for your quick answer. Actually I still use mysql for confluence. I did not change anything in the confluence settings, but out of a sudden this error occured. I attached an exceprt of both log files (atlassian-confluence.log) and (catalina.out.txt). I can't find the specific problem in there... :-(

Do you have any idea what could be the problem here?

Thanks a lot, Sebastian.

[Amalia]

I think it would be great if you could attach a full atlassian-confluence.log here :) the Null Pointer Exception does not explain anything. Usually the root cause of the error comes before that :)

[Sebastian Buckpesch]

couldn't attach the full file anyhow... I hosted it on my server: http://www.app-arena.com/de/files/temp/2013_01_atlassian_answers/atlassian-confluence.log.txt

Sebastian, I have checked the log but it includes all the NullPointerExceptions (I suspect you tried to refresh the browser every time). I would recommend you to stop Confluence, clear plugin cache and then start Confluence. See if this fixes the issue. Otherwise, see the log and search for "build #" (which is the last restart that you did) and see if there is anythign useful after the restart. attach the recent log here or go over to https://support.atlassian.com/ to receive our support :)

Thank you. This solved my problem. :-)
