I downloaded the latest version of K2 and am now trying to import articles and categories from within my Joomla 3.2 installation.

It appears most, but not all, articles and categories have been imported. During the import I got a message "fatal error: maximum time 30 seconds..." Some sub-categories were not imported. Some articles where not imported though their category was imported.

I understand I should not click the import button again since it may duplicate what has already been imported.

I have a very large database with thousands of news articles covering several years.

Which importing tools would you recommend?

I have a similar problem. Is there workaround to this problem?
