I've been making Joomla! sites for a while, and I'm used to seeing the white screen of death etc. I know how to troubleshoot those, and I know when they are happening. But this is different.
It's still a white screen, but on the whole, the DOM loads, and some of the containers. It seems to me that there's some kind of a database error, because the structure loads, but the content doesn't. No error actually shows, and no content, but if you examine the HTML you can see it is there.
Worse still, it's inconsistent, sometimes reloading the page makes it work. So it's really hard to troubleshoot. I had one that was doing it consistently, I examined the html and it started working again, and now it's working consistently. I can't troubleshoot something that works.
It's happening across multiple sites, using multiple templates, and template providers. Using the same host. It seems to be only on Joomla! 2.5
Can anyone else explain what is happening, have any others had the same issues?
