List of plugins was not loaded: Invalid Http response
Whenever I run Intellij and go to settings -> plugins -> browse repositories, I get an error message popup "List of plugins was not loaded: Invalid Http response". No idea why. I'm not behind an HTTP proxy.
In researching this issue, I found some other posts which point to invalid xml.
http://devnet.jetbrains.com/message/5284025#5284025
http://devnet.jetbrains.com/message/5267778#5267778
http://youtrack.jetbrains.com/issue/IDEA-56538
I did find one xml error in availables.xml in .IntelliJIdea13\config\plugins but it seems to recreate this file each time so fixing it doesn't work. The xml problem is in the entry for the Log4JPlugin:
<idea-plugin downloads='29099' size='110269' date='1302711954000' url='http://plugins.intellij.net/plugin/?idea&amp;id=13'><name>Log4JPlugin</name>
It should be & instead of &amp;
In Manage Repositories the only repository is http://plugins.jetbrains.com. When I try to use http://plugins.jetbrains.com/?idea instead using the Check Now button, I get a different error: "Plugin descriptions contain some errors. Please, check idea.log for details." The error in the log (provided below, is the same, though as for the other error.
The log from startup to the error is:
