I had a similiar problem, i.e. when i clicked on the events button i recieved a blank hanging page.
In my case it seems to be about the localisation. If i set my admin page language as "english", problem disappears. If i set it back to "turkish", events page hangs
I couldn't find any workaround yet. So my admin page is still set to english.
Hope this info is helpful.
Here is some more info about the problem :
This problem does not appear on my local XAMPP server.
When i upload my site to the GoDaddy Server, the problem shows up.
(GoDaddy Server : SQL 5.5.33 / PHP 5.3.24 and my local (XAMPP) SQL 5.6.16 / PHP 5.5.11)
Attached is the image of my local server screen shot.
On my local server events panel does not crash or hang.
Here we may be seeing some hint.
Marked with the red lines, we can see that the month names here are in Turkish but cannot be shown correctly. (i.e. turkish characters "ı" and "Ş" shown with "?" marks.)
