Starting a new thread since the conversation has diverged. I'm noticing that with both mediawiki 1.11 and mediawiki trunk there many, many templates missing after running the enwiki-20071018 dump through mwdumper. I searched around and noticed this tread: http://www.gossamer-threads.com/lists/wiki/wikitech/108392?do=post_view_thr… , where Jeff mentions that increasing the memory_limit and execution times allowed certain templates to render. I've incorporated these changes and still notice that certain templates are missing. Even more, when I try to copy the template from en.wikipedia.org and create the template on my local dev machine I get the following error, both with 1.11 and trunk: """ A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden) from within function "efUpdateCheckUserData". MySQL returned error "1146: Table 'wikidb.cu_changes' doesn't exist (localhost)". """ Shouldn't the installation script have created this table? I ran mysqlcheck and everything is fine (See below). I was under the assumption that the dump contained all the templates in use. Was this assumption incorrect? If that is correct what is not happening in the normal setup (by browsing to config) that is missing?
