In the past two days, Mary Cooch, Howard Miller and Mary Evans have all burgled my site and had a look-see. First, thank you for that.
Today has been a weird day. However, it seems that the site is now largely working properly. I'm not sure why. There were problems with hostgator which they promised to fix this morning - I'm assuming they did, although whatever they did made no immediate difference.
Howard managed to replicate some of the problems I'd found on his own site, though I'm not entirely sure which ones.
Fed up, but at least content that there was something wrong, I reported a bug. Then I switched off the pc, totally fed up at wasting my time, and put some food in me.
5 hours later I logged on and discovered that the flv and mp3 files that I'd tagged on the front page as part of the bug report were working. My logs suggested Mary Evans had been up to mischief, as she quickly confirmed.
Mary had apparently turned on the swf filter, which I'd already tried, and also the 'allow embed and object' filter. I think she also moved the mediaplayer filter to the top of the list. Whatever that means.
I went to look at the security report and two red boxes were threatening to mug my mother if I didn't turn off the offending filters. Curious, I turned them off. The flv and mp3 continued to work - in firefox. I spoke to Mary and admitted I was baffled.
I then tried the site in IE9, first in 64bit and then 256bit (why are there two versions?) and discovered that in the 64bit version the flv and mp3 were still just line links, but in the other version they were working normally. I also tried chrome, and everything was working with that too. I went back to IE9-64 and entered the course and added another flv to a lesson. It showed as a link only. I then went into the site using firefox (3.6) and the flv displayed and worked as it should.
I have absolutely no idea now what the problem was, or why it continues to affect one of two IE browsers (or why I have 256 and 64 bit versions of the same program). However, it is now plainly less of a problem. Well, provided users don't use IE9-64.
If anyone has any ideas, I'd love to hear them. Howard, I'd love to know what problems you identified with filepicker, because I don't know what they were and if they still apply! I suppose I'd better scratch the bug report, even if I don't know why...!
Thanks to those who offered help and suggestions; most appreciated. When it explodes again and refuses to work tomorrow I'll need to ask you for help again!
