Confirmation popup position with PHP7

Hello.

I'm trying to migrate my website from PHP5.6 to PHP7.0, and I'm facing a problem with the confirmation popup position (when you want to add or remove a connection with another member).
The popup, which should be centered, appears at the bottom of the screen (see attached image).

I've tested (and noticed) this problem in Firefox and Chrome.
Back to PHP 5.6, the popup is centered again.

Thanks in advance for your help

That's entirely jQuery and has nothing to do with PHP7. More than likely your Joomla template has the viewport set wrong in HTML. Switch to default Joomla protostar template and see if issue persists.

Thanks for your support !

You're right ! With the Protostar template, the confirmation popup is centered again.
So the issue seems to come from my template.
But I don't understand why I don't have this problem with the PHP5.6 version of the exact same website, same configuration, etc.

By the way, what is the viewport of a template ?

You'll need to contact your template developer for support or compare the HTML structure of your template with protostar to see what could be wrong. PHP should have absolutely no effect on this, but I've no idea how your template was designed.

Yes, PHP should not have any effect, but it has, unfortunately. :blink:
Since I'm still waiting for an answer to the last question I've asked to the template developer (1 or 2 years ago), I think I will have to fix it by myself...
Thanks anyway for your support.

You may just want to consider a different template in that case. I recommend a Bootstrap 3 powered template as it should style CB nicely as well and anything else using Bootstrap 3.
