I have no idea where that comes from, that is not standard GD … ??

Add this to your CSS (you might have to adjust the number):

.geodir_full_page {
    margin: auto;
    max-width: 1140px;
}

The related listing tab on the detail page will only show if there are related listings as per your settings at GD > design > detail > RELATED POST SETTINGS

You are not using the Payments Manager, but if you did, you could for example remove the related listings tab for featured listings, and leave for others.

You can adjust the CSS to change the font etc, have a look here for a guide:

I’ll get Paolo to have a look at your first question.

You can change

You must be <a href="%s">logged in</a> to post a comment.

in the GD core language file: https://wpgeodirectory.com/docs/translate-core/

Clever solution, thanks for letting us know.

Have a look here if you want to have a go yourself:
https://wpgeodirectory.com/adding-a-payment-gateway-to-payments-manager/

I’ll get Paolo to have a look at your question too, he might be able to put you in contact with a developer who already has created a few different gateway plugins.

It does not show as a problem for me because “Like” is a lot shorter than “Gefallt mir”.
I guess changing your CSS like this might help:

.likethis iframe.facebook {
    width: 120px !important;
}

I have added that at GD > design > scripts in case you need to change the width.

Does that solve it? Because I cannot see it …

Try resetting all yoast settings to default. Sounds like a Yoast redirection problem, or stripping categories from the URL. Have you asked at Yoast support?
