Pasting Large Amount of Text Through Paste-from-Word TinyMCE button leads to Whitescreen upon publishing

[mkgold]

I needed to paste a large MS Word document into a WordPress page, so I used the Paste-from-Word button on the Visual Editor to do so. When I tried to publish the page, I got a whitescreen with the URL /wp-admin/post.php

After testing the problem in various ways, I determined that the problem arose only when the amount of words in the page were more than 10,000. The page posted fine when there were fewer than 10,000 words.

Using WordPress 3.1, CommentPress Theme, Mac OS X 10.6.7, Chrome browser

It would be useful if you could add the following line to wp-config.php and tell us what you get:

define('WP_DEBUG', true);

Ignore other notices that may appear until hitting the 'Publish' button.

Thanks. I added that line to wp-config.php and did see an error message on the post-writing page. However, When I pasted text through the Paste-from-Word tool and then hit "Publish," I again saw a white screen. No error messages appeared.

For what it's worth, here are the error messages I saw on the post-writing page:

Replying to mkgold:

Most of these errors indicate that the Commentpress plugin needs an update.

Few more questions:

• Are you logged in as admin on a single install (i.e. do you have unfiltered_html capability).
• What happens if you try switching to the HTML editor and back before publishing?
• What happens if you paste the Word content into the HTML editor and publish?
• Is it possible to try this with all plugins disabled and with the Twenty Ten theme?
• Does adding define('WP_MEMORY_LIMIT', '128M'); in wp-config.php solve the problem?
