I'm not really a web designer, but a friend has asked if I could help with an issue their site is having since I once helped them update a couple of their pages. The URL in question is http://www.intec-comms.com/ and the issue is that apparently the front page will suddenly display in question marks. I've been able to reproduce the issue - when first going to the site, it will show up as all question marks, but refreshing will occasionally bring it back to normal (it's in Japanese), but then another refresh will bring back the question marks.
As far as I know, nothing has been changed to the code since I last updated it almost a year ago. It almost looks like an encoding issue, but I've modified the current "charset=utf-8" to "Shift_JIS" and that just made things worse.
I know nothing about php, so I don't really know where to look but if you had any suggestions I'd greatly appreciate it!
