Today I was browsing the store, looking for plugins, and stopped at this page
to check it out. Since I liked the addon idea I decided to reward its author with a Like. However, the moment I clicked the Like button an error message popped up, and neither reloading the page nor hard clearing the page cache would fix it. The problem occurs a bit all over in the store section at the moment of writing this: Like or Dislike a plugin will trigger the error.
