Importing content from WordPress site to WordPress site fails after file upload

Probably PHP on the production server is timing out. Increase your timeouts, maximum upload size, etc., in the php.ini file for that directory, or for the server overall.

I just checked it and the max post size is set to 8M (my XML file is 698K). The memory limit is 128M. The max execution time is set to 30 and the max input time is set to 60. I am not a php expert, but that seems like that should be enough for what I’m trying to import, does that sound right to you?

The max execution time is set to 30 and the max input time is set to 60

Raise those to 240 each and try, then set them back afterward.

Tried raising both to 240. It had no effect. Is there a log file where any errors that might be getting thrown could be seen?

Try Googling for your OS and error logs. This is really a server issue and not really WordPress.

I’ll do that, is it possible a permission issue could be the cause? I think there may be a permission issue with the uploads folder. Do you know if that is where it tries to put the XML file when it uploads it?

Yes, WP will try to write a temp file in uploads. See Changing File Permissions ? WordPress Codex

ok, we were able to locate the log file. I’m getting the following error in the log every time I try to import:

PHP Fatal Error: Class ‘DOMDocument’ not found in /var/www/wp-content/plugins/wordpress-importer/parsers/php?import=wordpress

Does this mean there is a problem with the plugin itself or with the XML file I’m trying to upload?

Search the forums for “PHP Fatal Error: Class ‘DOMDocument'”

Thanks! That helped a lot. I didn’t have php-xml installed.
