There has been an issue that took a while to track down where petitions wouldn’t display despite there being a shortcode on the page.
Thanks to Tobias author of another plugin. Working with Steve from Florida he noticed a non breaking space being inserted in the example short code in the list of plugins.
Instead of [emailpetition id="2"], what people were copying and pasting was [emailpetition id=”2″] which is a special space that looks like a normal space but acts differently in a wordpress plugin.
Knowing the problem, it was a really simple fix that was worth pushing as an update on its own.
