Hi,

I have been running Blog4Umbraco on my site (http://www.bayshield.com) since it was first released in December last year  (with no real problems) however I recently been informed by two separate people that they have seen my site returning an error "Error parsing /xslt/blogListPosts.xslt".

I checked my server logs today and found the following error which coincides with the times users have experienced the issues.  Based on the error message I am guessing that the cache is expired and the database is getting called to refresh the cache.  What I don't get is why the site would then subsequently work.  

Does anyone have any ideas on what might be causing this, or the best path to take to try and identify/solve it?

Thanks

Aaron
