I put a post here yesterday (or thought I did but it seems to have disappeared maybe I am going senile).
Anyway let's do it again. I now have the internet on steroids here, it is VERY fast!!.
I tried uploading my 100mb test file that was giving me the white screen of death AND I got a message from our site saying that the file was too big! So already an improvement. I then upped the limits that our site sets and it worked fine.
Now I don't not think me upping the internal site limits will have any effect as it was rejecting a successful transfer in a graceful manner.
But what all this does mean is that the problem is one of time and not file size! We were seeing it with larger files as they take longer therefore causing the time problem. If that makes sense.
Anyway I have upped limits where I can so we'll see what happens ... but at least I know what the inherent problem is (or hopefully was).
Best regards
