CMS Articles HTML issue

[Snape]

Hi all,

I recently inherited the administration of our forum and since the 4.2.2 update a huge number of errors have turned up.

In the CMS articles on our frontpage, some have the HTML content displaying perfectly fine, others have the code exposed. When I go into the aritcles to check the settings, the ones that work have the HTML options in the right control panel. The ones that don't display correctly don't. They have been created by 2 different authors, both of whom have since moved on and cannot or will not help fix it.

How do I re-enable the HTML option in the articles WITHOUT having to recreate them from scratch?

I've already checked the permissions and made sure that I'm able to use HTML content, but I think the problem is that the person that created the non working articles never switched on the HTML option when they originally made the article OR something in the latest update screwed another thing up.

Any help here would be appreciated
