Used it many times in the past, first time using it since upgrade to 1.5.1

Get as far as the drop down menu for which clients I would like to send to (able to select), then click 'send'

Screen almost instantly goes back to Admin home screen, with no emails sent.

I do not see the sending screen.

So far...

Have checked email settings... but this has never been a problem in the past.

Any help appreciated

all the best and Merry Christmas / Happy Holidays

Phil
