how can I display my component errors?

[Segolas]

I'm getting crazy with a blank screen of death on my component. Obviously it works fin on my pc, but it is white online.

Is there any  way to let joomla show *all* errors, warnings etc etc?

How can I understand what's wrong if I can't see any error?

I have found from experience that testing in a Windows environment can cause you to miss certain subtle problems. For instance, Windows does not enforce case-sensitivity on file names. You might check that first. Also, your files may be in DOS format and may have to be in Unix format, or even UTF-8 format (Joomla 1.5). Then there is the permission thing, which is not usually an issue in Windows. However, many webhosting services are setup such that files you upload are owned by your user account whereas files created by a PHP script are owned by the webserver daemon (https, nobody, etc.). You need to ensure you have at least global read permissions on all the files comprising a Joomla site.

Hope this helps.

I'm on a linux box (ubuntu 7.04). So permissions and other stuff are allright.

I really need to see what is wrong.

The setting you need to change is in php.ini, which your host may or may not allow you to override.  Contact your host regarding this.

mmm Maybe I can do this via htaccess... do you know which php flags are involved?

[bascherz]

I assume this is an error that you can't see by setting error reporting to Maximum in the site back end? That won't help with 40x errors, but it works pretty well for coding errors. The error messages are output directly to your browser.

I just ptu that option to maximum and debug to yes. But this helps only on localhost. I think ianmac is right and is something  that have to deal with php.ini on server.

But I solved in this "dumb" way:

1) Commenting all the target file.
2) Then uncommented first line of code.
3.a) the page display --> then the error is not in the first line, uncomment the second and so on...
3.b) the page doesn't display? --> maybe the problem is here... maybe not...

If you really want to do this right then get Eclipse and the PHPEclipse plugin and use it with XDebug to debug your component.  It'll make things a lot easier.

You will get more from changing error reporting in PHP, but no where near what you get with XDEbug.

I've got phpeclipse. Ad in localhost everything works fine. Every error is shown. The only problem is in the host.

I ask the host managers if they can do something
