I can not believe why this should happen but....

In my config-Introduction text for registration setup I had this = Your user name should be between 2 & 20 letters in English<BR>
<font size="1">You CAN NOT use -, _ , &#,@, an email or Chinese Characters.</font>. <BR>
It will also check other details
and as I pointed out in my first posting =

After upgrading to 1.7.1 from 1.7. the Profile image/avatar field which should be Required does not check them now.
I have rechecked the 'Community Builder Field: Edit [ Profile image ] ' set to YES
in the config all set the same as before both YES
Set to "Yes" if you want registered users to have an image (manageable through their profile) & Allow Image Upload Set to "Yes" if you want registered users to be able to upload an image.
the Ajax Username checker & email checker also has stopped

I REMOVED THE <font size="1"> </font> tags and it works
Why should having a font size tag mess up the page ??

Cheers
