I am having a problem with my permalinks. The permalink structure that I have for my posts is - Month and name (common setting).
When I create a post the month and name setting works fine, inputting the correct values i.e. mysite.com/2014/03/sample-post/
Now when I try and make a correction and update the post the permalink changes to mysite.com/-0001/11/sample-post/ - meaning the post can no longer be found.
The site is an international/multilingual site using WPML. I also have bullet proof security installed, latest versions of each. htaccess is writeable but secure .htaccess is enabled.
Could anyone give me a clue as to what might be happening?
