[Moin-user] CacheNeedsUpdate error upon creating new page

[Rob Kirkbride]

Hi,

I've been tearing my hair out with this problem since moving the Wiki
instance from a backup.

If I edit a page, add a new Wiki link and then attempt to access this new
page, I get the error below.

I've tried clearing cache directories, checking permissions etc.

Can anyone help - I've been struggling with this for weeks, having to add
pages manually by copying inside the directory structure and then renaming
which is obviously useless!

A problem occurred in a Python script. Here is the sequence of function
calls leading up to the error, in the order they occurred.
