Hello,
I got 4 times the "500 Internal Server Error" when updating to 3.7 the following website:
> http://www.hostelsmith.com
But this one worked good at the first try, however it took around 3 minutes...
> http://www.agenceducapdantibes.com
Note: this one has got the French version of Wordpress
Both are located on the same server.
Below the error message:
