I have seen that lately chrome users have been experiencing an Error 324, that with Firefox result in a simply WSOD.
I read the solutions other user had proposed, but I was working with a local devel site so my situation was different and the solutions there didn't apply to me
I had the problem trying to install a module of mine. My module is nothing special, just adds few content types with fields and istances. The strange thing was that few lines of code made the difference. If I commented the lines installing one of the instances about a "node reference" field everything was fine again. On the other hand, commenting an instance of another type wasn't working.
Since I was sure the code was fine I tried to commenting another similar instances instead of the previous and everything was still fine. I run in debugging mode and saw that my code wasn't throwing any exception but the code hanged elsewhere.
I tried
So I started disabling core modules to see if something changed and found out that without "comment" the installation did just fine. I also tried to disable other but the issue was still there.
So I'm left with two major suspects "comment" and "node reference", or more likely a combination of both, as it seems too many node reference instances throw comment in another universe.
