Unable to post comment

Hey, so I have lots of issues with the answer comments right now :/
(I deactivated all other plugins by the way)

I hate to be the bearer of bad news but on the other hand I guess it’s better to notice these bugs as soon as possible and fix them so that everybody can have a great Anspress experience, don’t you think 🙂 🙂

So here are the bugs I have :

1) With my current template :
If I click “add a comment”, it slides down the comment form (as it normally should) but then it immediately goes back up, so it’s impossible to type anything. What could be the reason ?

2)If I enable Twenty-Seventeen, the bug is different : the comment form displays normally, but after I click “comment” I get the message in red “you’re typing too fast. Take your time before you post a comment” and the typing window is still here as if it didn’t work BUT it actually saves the comment. So I actually ended up saving the same comment 5 times 😛

3) (with Twenty-Seventeen) If I am not logged in, it displays the comment form as if I was logged in and when I click”comment” it says “unable to post comment” without any further explanation.

4) (with Twenty-Seventeen) If there are comments, when I click on them nothing changes, they do not appear.

Along the way (I think it was during #3 but I was unable to reproduce the error afterwards), I got the following error message in the logs :
[07-Jun-2017 18:17:10 UTC] PHP Fatal error: Call to a member function get_error_message() on boolean in (……)/wp-content/plugins/anspress-question-answer/includes/comments.php on line 167

Except for that, no PHP errors and nothing in the console, for all these bugs.
I’m puzzled.

Thanks for your help 🙂
