If the comment is entered via Desktop (as I just did) and then the page is viewed on a Mobile phone using Firefox the issue of the white right margins and the header being stretched to the right and bottom remains. Please see the attached two photos - a screenshot of the page in which the comments were added.

Please be advised that I removed the admin rights granted to you two weeks ago. If you need these rights to further investigate the issue, please lee me know.

Thanks for all your help

We just checked it via Xiaomi devices and everything works fine. 

Please test it on one more time on incognito mode.

Please let me know when you no longer need the admin rights that I gave you, so I could delete that user. Thanks

Please send the admin login details to infogvectors.com email address. We'll try to find some solution for you. 

Hi,

I don't know on which device the video that you sent was recorded on. Unfortunately, the issue does exist, at least on the three mobile phones that I tested (Xiaomi Pocophone F1, Xiaomi Mi A1 and One Plus 6).

The attached video was recorded on Xiaomi Pocophone - as you can clearly see, the header extends to the right and there is a margin on the right hand side all the way down.

I truly appreciate all the support provided and your efforts to help me resolve the issue. I understand that at this point there is nothing further that can be done.

All the best

We've checked many times. As you can see in the recorded video below there is no such an issue.

Hi Astghik

Attached please find a screenshot of the CSS code that I have under Styling. I received two pieces of code and they are both included.

The issue persist but ONLY when comments are entered via Desktop. When I entered comments via Mobile phone the header was OK.

Attached please find a screenshot of the page when I experience the issue - header is starched to the right (and somewhat to the bottom) which creates wide margins on the right side of the page.

Did the further information provided (issue occurs only when comments are entered via Desktop) helps in any way? 

Thank you for all the support so far.

Please keep all codes provided by Elvina and add the code below as well. 

section.has_ae_slider {
   width: 100% !important;
}

I've looked at the links that you provided and understand that you believe that it's a scrollbar issue?

Yes, indeed we think the issue is related to the scroll bar. However The code above should solve the issue. 

Please don't forget to check on incognito mode.

Hi,

I've placed the new code under the Styling section of wpDiscuz plugin, along with the previous CSS code that you sent. Unfortunately, the issue remains as it was after I entered the first CSS code. If I should have placed the new code in another location, please advise where.

I've looked at the links that you provided and understand that you believe that it's a scrollbar issue?

Pleas let me know if you think that there is any piece of advice that you can give me. In any case, I want to thank you for all the effort you put in trying to help me solve the issue.

Please try to following CSS code and check again:

html, body {
overflow: -moz-scrollbars-none;
}
