Error logs not being written

[jeking]

I'm working on an upgrade and getting blank pages. When I look in my logs folder, there are no errors. When I enable STRICT_ERROR_REPORTING, I do see the errors on the screen.

My logs folder is writable and I have not made any changes to either configure.php file relating to log files or folders.

I checked with the host. They did recently disable PHP functions:
show_source, system, shell_exec, passthru, exec, popen, proc_open, ini_set

Are any of these require for log files to be written?

No. Those are not required for log writing.

Logs are written to /logs/ if the folder is writable (by the user account on the server which is running PHP/Apache), and if the enable_error_logging.php file is present in the extra_configures folder in both admin and catalog.

The DIR_FS_LOGS constant defaults to pointing to the /logs/ folder, and is no longer set in the configure.php file unless you've set your own define for it there for the purpose of overriding the default.

The folder is 755 and I also tried 777. The folder has the same ownership as all other folders.

enable_error_logging.php is present in both the admin and catalog folders.

Here's an example:
http://wheatonwebsiteservices dot net/zen155/graphics-cards-c-1_4/matrox-g400-32mb-p-2

Shouldn't this error be logged?

[DrByte]

Yes, I would expect it to be logged.

Maybe something about the server's configuration is denying application-level overrides to php directives.

While the PHP directives may not be needed for error logging, removing them solved the problem. I'm getting my error logs again.

It could be a server config that needs some in some way.

Er, without the benefit of ini_set the majority of the functionality provided by /includes/extra_configures/enable_error_logging.php is moot.

Thanks for pointing that out. When this was done, I did notice a plugin (CSS JS Loader by Numinix) stopped working. It had a call to ini_set. Commenting out that line resolved the issue and got it working again.

Argh. I missed that in the earlier post.
Yes, disabling ini_set would be a problem.

Just for my edification, what webhost is this?
