Problem description:At the company I use Zend Studio for Eclipse Professional Edition to write PHP projects. It’s a great piece of software, but it still has plenty of bugs. This morning it suddenly refused to start — it got stuck on loading org.eclipse.php.core and the progress bar never moved again. I tried reinstalling over the existing installation and it still didn’t work, which left me baffled. Was I going to be stuck at loading org.eclipse.php.core forever?
