When adding a new article to the knowledgebase I click save and rather than it being added to the knowledgebase I am prompted to 'open or save manage_knowledgebase.php'

Have you modified any of the HESK files? Try the original unmodified ones.

Thanks for the quick response Klemen.
Other than the header everything is original.

Hmm, strange. It would seem as if the server didn't properly process PHP files, but then the same error would appear with other files.

Any chance I could test it (you can send details over private message)?
