"You must request at least one space to book an event"

sorry but this works on our test sites however just to narrow down the problem and help us debug the issue is it possible to try the following temporarily:

– deactivating all other plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems

Looks like it is the theme, I am using Echelon from MySiteMyWay.com. This is somewhat problematic moving forward, other than obtaining another theme do you have any suggestions.

It sounds like you’re running into the problem outlined in this post:

It seem due to jQuery serializearray() function. I do NOT know the reason but I suggest how to fix the code of EM

at ..\classes\em-ticket.php line about 509

<?php if($zero_value && !$this->is_required()) : ?><option value=’0′>0</option><?php endif; ?>
<?php for( $i=$min; $i<=$available_spaces && $i<=$max; $i++ ): ?>
<option <?php echo ” value=’$i’ “; if($i == $default_value){ echo ‘selected=”selected”‘; $shown_default = true; } ?>><?php echo $i ?></option>
<?php endfor; ?>
<?php if(empty($shown_default) && $default_value > 0 ): ?><option <?php echo ” value=’$i’ “;?> selected=”selected”><?php echo $default_value; ?></option><?php endif; ?>

ie at value at option element

Thank you very much!

correction ie add value attr at option element
