I’ve had a few problems with a Safecracker page recently, most of the time it works OK, but occasionally doesn’t save properly.
I checked code and all I could find was a missing space between the name and value parameters, what do you think, would this affect anything?
eg:
{exp:safecracker}
<input type="hidden" name="who"value="{member_id}"/>
<input type="submit" value="Go" />
{/exp:safecracker}
