server error on posting new changes to an existing tutorial

[arin...@gmail.com]

Hi.

Other than not being able to figure out why gots still can't send mail, our installation has worked pretty well. But now, one of our librarians is suddenly getting a server error in the browser when she tries to edit an existing guide. The edit feature used to work just fine. In fact, it works now, it just throws an error even though the data changes are being saved. The server logs show:

[Tue Jan 13 13:12:49 2015] [error] [client IP_hidden] PHP Warning:  file_put_contents(/var/www/guide_on_the_side/app/tmp/logs/error.log) [http://php.net/function.file-put-contents]: failed to open stream: Permission denied in /var/www/guide_on_the_side/lib/Cake/Log/Engine/FileLog.php on line 144, referer: http://www.lib.siu.edu/guide_on_the_side/tutorials/edit_content/17

My first attempt was to give universal access to debug.log and error.log and try the changes again. I looked in debug.log afterwards. The only entries in debug.log (there are many) are all variants of this:

2015-01-13 13:39:07 Notice: Notice (8): Undefined index: Role in [/var/www/guide_on_the_side/app/Controller/AppController.php, line 39]

The last entry in error.log is:

Server configs have not changed, file permissions are the same as they were when it worked, and server has no disk space or other operational issues that I know of.

Any ideas on things I should check? Happy to send any logs or configs which will help!

Since I'm posting anyway, I may as well repost a snippet of our config.yml - re: no email being sent (even though other server apps send mail just fine)

application_title: Guide on the Side

Thanks for any help offered,

Hi Doug, 

Sorry for the delay, but it looks like you need to run

chmod -R 777 app/tmp 

See the README for more info.

Thank you, yes I had done that, but the error persists. A blank frame and error logs, but the submitted data is being stored.

Doug,

Who owns the files in the tmp directory?  Could you power the results of `ls -alR` in /app/tmp along with the username of the account that runs your webserver?  I think this could be an issue where the ownership of the files is messed up.

I issued chmod -R 777 tmp and this time whatever I missed must have
gotten changed and resolved the error. The content manager confirms
that she no longer gets a blank screen when submitting changes. Thank
you!
