Okay,

Just to complete this discussion. I upgraded to IIS7 hosting with IIS’s rewrite module.

Didn’t have the problem at the beginning, but then noticed it at some stage. When comparing the default install to the actual install I found the following in wp-config.php as the ‘only’ difference.

define(‘WP_MEMORY_LIMIT’, ’64M’);

After removing this the 404 pages started displaying again. Then I added the statement back and it still displayed.

So, I don’t actually know if this is the cause of the problem, but after removing it and then adding it back I seemed to have fixed the 404 pages not displaying?

Hi Otto42,

If I do not have an IIS6 custom error page set only the root of the site works ie the index template?

If I add the custom handler as specified everything works as expected apart from the 404 pages that are ‘blank’.

I’m experimenting on http:/preview.tawnylion.com/ don’t want to mess with the version at tawnylion.com.

The preview site has vanilla wordpress installation. No plugins and using default theme, currently configured to use permalinks set to /%postname% has no htaccess file (no redirection) and the custom 404 error handler.

All the links work as expected apart from when I ‘call’ an invalid url eg, https://preview.tawnylion.com/badurl

Okay,

I can confirm that this behaviour is the same on a completely fresh install of WordPress.

By default WordPress doesn’t seem to be able to ‘process’ Page Not found on my configuration. I’ve even tried different PermaLink structures to see if it makes a difference.

If I configure a custom error page (/index.php?error=404) or an error handler (ErrorDocument 404 /index.php?error=404) in the .htaccess file I just get a blank page.

So, the question becomes, why can’t WordPress process and display /index.php?error=404 correctly?

At least I found a reason for the non-blank page on Internet Explorer.

Thanks to perishable press for the details.

Apparently IE uses its own 404 page if the 404 page being shown is too small.

Now, still no idea as to why 404 displaying as blank.

Mmmm … just as I’ve posted this the ‘behaviour’ goes and changes.

On Firefox 3.5 I get the ‘blank’ page, whereas on IE 8 I get the default IE 404 error?

The logs still indicate intermittant premature end to processing. Some sort of timeout?
