I tried to update to 3.7.1 via update on dashboard and received error 500 indicating server not available. I was able to access all o0ther aspects of the admin dashboard including posts, delete comments etc.
I looged a call with my host who eventually said I should get intouch with wordpress forums as it appeared to be a code issue. As I tried to log issue here today and gathering info, I now discover that instead of error 500 coming up I get a blank screen. I can backspace to the dashboard. I noticed on the forum reference to similar issue with earlier version and suggesting to disable plugins and then retry update. When I went to plugins page i got same blank screem.
I have a single site guidefishingireland.com...i have never modified any code myself and as far as I remember I has successfully updated to 3.7 a couple of weeks ago and after that, updated some plugins prior to trying to update to 3.7.1.
