I had the previous version of Jetpack, along with other plugins, installed and running. This morning I updated to version 1.2.1 - the result being an inaccessible white page to any of my admin links e.g. posts, pages, plugins etc. I found a solution on the internet to deactivate all plugins via phpMyAdmin to access my admin page again. So, I did this and reactivated all plugins (Akismet, Contact Form 7, eShop for WP, Google Analyticator, Really simple CAPTCHA, Shadowbox JS, Shadowbox use title from image, WP pretty photo) one by one and it works until I hit Jetpack, then it is a white screen again with no access to anything. I tried the activation in different order of the plugins, but to no avail. So, now I have Jetpack deactivated, because it is not working. Any idea what could be done to get it back? Thanks!
