I've been digging around this site trying to find a solution to our problem. We have 4.5.3 installed. I'm sure that we need to upgrade it to a newer version, but I wanted to ask this question first.
Over the weekend, our site has stopped responding to users. When people type in our URL they see a white page and that it's loading, but it never does. Before, if this happened, it was because I had made a ton of changes in one day. I logged in to our hosting provider and opened and saved the web.config file to make DNN think it had changed. Then it would load just fine.
That worked this time around, but only for about an hour, then it went right back to the way it was.
We spoke with technical support and they said that our DNN installation was killing our application pool. We were running high on memory usage, 304MB at peak, and once they restarted it it was fine. But then it went down again. It is still down.
I'm trying to figure out what would cause this issue. Child portals off of this site that have their own external URL are running fine. There aren't any performance issues there. Any child portals that are still linked to our domain are not loading. We have a large site (509 pages) but this isn't something that should just happen overnight is it?
Please help me.
