Using the chat feature found on your website I resolved with the attendant the issue appears only in Chrome. Firefox and IE work fine. I have never had a situation with Chrome in my experience different than the users experience with Firefox. The problem still exists and I no longer use Chrome for your website.
Please describe informatively and specifically what your issue is. We hope after we solve your issue (subject to our support policy), this forum thread will be searchable by internet searchers, looking for help with the same issue but it won't happen without a text. Thanks in advance for your understanding.
The tool bar provided in your Joomshaper support forum is the place to look. The icons (subscribe, notifications and my user name with the drop down list) are not active. When I hover I see tips, however I can not select the icon to subscribe or to view my notifications or select the drop down menu items.
You don't need to subscribe to receive notifications on new replies made in your threads, - they will come to your email ibox automatically.
I am not sure why you can not select items in your drop down lists, like items under Notifications, for example, - they work for us pretty gracefully. I personally rely on them daily. I suggest you check how the toolbar icons work for you under other browsers/other computers.
