I see a "connection reset" error message after updating
This may occur rarely on Windows servers, and can be solved by increasing the thread stack size by adding the following code to httpd.conf:
<IfModule mpm_winnt_module> ThreadStackSize 8388608 </IfModule>
If your site is on a Windows server and you do not have access to the httpd.conf file, you will need to contact your hosting company for the change to be made.
