Hi Amandine,
I think all your map problems are related and Stiofan asked for FTP credentials to debug them here: https://wpgeodirectory.com/support/topic/cluster-not-working-2/#post-253950
The search button in on a second line because of css from the theme, please add this to design >> scripts >> custom css:
.geodir_advanced_search_widget .geodir-loc-bar .geodir-loc-bar-in .geodir-search input.snear, .geodir_advance_search_widget .geodir-loc-bar .geodir-loc-bar-in .geodir-search input.snear {
margin: 0 0.5%;
width: 32%;
}
.geodir_advanced_search_widget .geodir-loc-bar .geodir-loc-bar-in .geodir-search input.search_text, .geodir_advance_search_widget .geodir-loc-bar .geodir-loc-bar-in .geodir-search input.search_text {
width: 32%;
}
Let us know,
Thanks
