This is the what I and couple of other people have seen when trying to view wikipedia.org pages. It can show up on the first view of a page but the error goes away after refreshing it from a web browser from what I have observed. '''Fatal error: Call to undefined function: peplaceinternallinks() in /usr/local/apache/common-local/php-1.5/includes/Parser.php on line 812''' It looks to me like a typo (peplace instead of replace) unless that function has been renamed. I hope this helps.
See http://mail.wikipedia.org/pipermail/wikitech-l/2006-January/033522.html Resolving this LATER; reopen if similar issues crop up again. We should be better equipped now to localize the error to see which server has the corrupt pages.
Link to email thread results in 404 error, I guess the problem has been resolved. Marking it as FIXED.
This was probably from the old APC cache corruption issues, which I don't think are as common anymore.
