Hi,
This might be a js issue. try disabling other plugins to be sure if that’s the case. Also could you please check is there is any console browser error? Let me know the update. Thanks.
I updated the plugin, but the issue is still the same.
I have not error in the console browser.
In that case, probably you server is blocking the post request and you may see notice like this: ( https://www.evernote.com/l/AV2m3jX7-gNDE6kfzl816vGTYy7X53heBAMB/image.png ) in your firebug console, in such case, you need to contact with your hosting support. They will adjust it for you.
I’ve the same issue. No error in console, all others plugin disabled but the issue is still the same. My hosting allow all others post requests. Can you help me, please? Thanks.
