Guust

Play with this CSS:

#buddypress #item-nav div.item-list-tabs ul li {font-size: 9px;}

And what is the full path to the file?
Download a fresh copy of GDF, extrract on your local computer and check if that file is there. If it is there then it is a GD file. If it is not there, somebody got access to your server.

Can you post the URL of that page please, you can do that in a private message. Thanks.

I alerted one of the developers who will have a look for you.

Your payment addon languages files were not in the correct location, I moved them to /wp-content/languages/geodir_payments as explained here: https://wpgeodirectory.com/docs/translating-addons/

Your core language files had not the custom fields loaded, nor translated.
All I did was follow the instructions at https://wpgeodirectory.com/docs/translating-custom-fields/ and https://wpgeodirectory.com/docs/updating-your-language-files/ as suggested.

You did not translate the Buddypress integration either, I have done that now for you, so your add-listing page should be fine in the sidebar.

I have no idea how you created the homepage, since there is no access to your pages in the WP admin.
It works on the location page: http://derude.net/location/ when adding the widgets the usual way.
And it works on a post if I add the shortcode: http://derude.net/guust/

You do not get a progress bar as in the image either?
I exported 100 listings and imported them without any trouble again. So there must be an error with your changes to the file.
If you can link to the file we can have a look.
