I am getting the above error when users try to comment on posts at my site. This hasn't been happening long, and I did update to 4.4 for wordpress a few days ago. The last comment I noticed on my site happened Dec 16, and I do not know if anyone has tried since that time other than the user who reported the problem to me via my contact form. I have currently deactivated wpDiscuz until I know the problem is resolved. Once deactivated it did allow comments to be added again. I really like this comment system, so am hoping we can find a resolution.
Hi seamstobesew,
This is a JavaScrip conflict, it seems your theme JS affects wpDiscuz form ajax submitting functions. Please send admin login details to support[at]gvectors.com email address to allow us check and fix this issue.
