on your site?  sounds like a js conflict.  Is this something new?  was it working?  if so what might have changed?  theme or plugin updates?

try it with the browser console open and see what errors might be reported…

not sure

we will need some more info to go on…  Generally speaking, no issue with PMs… try the test I asked for and see what you get…

i dont know what to do..polls hasnt worked for  a long time either

any update on errors in the console?  sounds like a jquery conflict…
