Hi Lester,
Also from here: thanks for maintaining and supporting this plugin.
It seems that more people are experiencing this problem since I’ve seen more posts about this topic. We are also experiencing this issue, this time in combination with WP Fastest Cache. When disabling WP Fastest Cache, the polls start to work.
Can you explain how we can both use your plugin and a caching plugin? Maybe you explained this in the post above but I don’t understand exactly what you’re trying to explain with:
“The caching plugin can be in front of WP as well like Vanish or CF.”
Maybe the issue is also related to this post:

Thanks!
Same issue here. I’ve e-mailed the supportdesk for this. If the bug persists then I’ve asked for a refund.
