Error accessing user page
Fragment of a discussion from Support/LiquidThreads
Purged the page cache directly by editing the URL (?action=purge). It's working now. Thanks.
This is an issue that we have been investigating for the past few weeks with our caching server. Normally you do not get this exception, but you would get an incomplete sidebar. While we are investigating this, we know that about 50 page views will get this error every day; without it, we would not be able to solve it.
