plugin load failure results in blank page

[sneakyimp]

I'm trying to set up a local copy of a Joomla site on my linux development workstation and when I attempt to login (enter user/pass, click 'login') then I just get a blank white page. I tinkered around in the code a bit until I determined the cause. Line 139 in the file administrator/components/com_comprofiler/plugin.class.php apparently causes a fatal error -- but there is no error message or anything.

I think the reason is because, although the database has a record for this plugin, the directory containing the plugin does not exist on disk.

Is there some setting that would cause Joomla to show an informative error that I could turn on? It was quite difficult to find this error.

You check the log file(s) of Apache and/or php.

Set Site -> Global Configuration -> Server -> Error Reporting to "Maximum" or manually update the relevant line in your configuration.php file like this:

Code: Select all

$error_reporting = 'maximum';

The blank white page is sometimes caused by PHP limitations. Maybe try increasing the memory_limit and execution time via a custom php.ini file or similar:

Code: Select all

memory_limit = 256M
max_execution_time = 30
max_input_time = 60

Thanks for the response.

As I described in my original post, the error occurs when I try to login.

Code: Select all

$error_reporting = 'maximum';

I have done this and the problem persists with no error message. Does Joomla have its own log?

I had a devil of a time locating the appropriate log for PHP errors, and now that I have found it (and verified it is where PHP errors get written for this domain) I see that this blank page doesn't produce any PHP errors.

Joomla logs can be found in the /logs folder but apart from login success/failure, there's usually not much useful information.
