I am currently developing a website in DNN and I am near to completion, most of the time the website will be fine displaying all its content with out any problems.  Then once every week or so, usually when im adding files, the websites content will disapear with an error saying  "array is out of bounds".  I cannot access any of the site setting and all of the pages apart from the home page have disappeared.   I have found that an IIS reset will get it back up and running with no problems at all.  As you can see this is not what I want and we are currently looking into the database to see if some errors are cropping up in there, with no luck.  I was hoping that maybe someone  may have some ideas on what the problem could be and maybe even a solution!
Many Thanks,

Tom
