When downloading the
ad widget and the recent comments plugin can't be downloaded using the dashboard. You will receive an Error 500.
Server error status: Internal Server Error 
Please check - all other plugins are working fine.
Could yu please make this dropdown list of plugins sorted A-Z - I have written that request already more than 3 months ago the first time and until now it is still a complete chaos sorting and very hard to find the correct plugin - i.e. I could not find ad widget!
