A Wordress 2 Pommo Implementation
Probably because you have modified the Pommo success / error templates. This is not forbidden, but it's mandatory that there is the div with the id "alertmsg" ..
It looks like this :
<div id="alertmsg" class="error">Why there is an error</div> or on success:
<div id="alertmsg">Welcome ..</div>
This is required! Dont remove it! But you can hide it (style="display:none") if you want.. the "class=error" is also required!
Also remove the "Confirm URL" in Setup -> Configure -> General
You could replace the process.php in "path-to/pommo/user/process.php" with the one provided in this plugin .. But no warranties! If the Pommo developers will make any changes or some!
I've tested 16.1, the current stable in 2009-04.
Please go here: http://pommo.org and ask the developers.
Because the Pommo developers kindly provided this feature in Pommo.
