I also experienced the same with WP Castle theme and this is what I have done to fix the bordered images:
/* fix map images */
img.olAlphaImg, img.olTileImage {
border-style: none;
border: none;
}
However I can’t seem to figure out how to fix the the map Framed Cloud Pop-up when you select a marker. Because it uses css image and css positioning instead of css border-radius it is all messed up in the WP Castle theme.
I also tried to just hide the pop-up images to no avail:
/* fix map pop-ups */
.olFramedCloudPopupContent {
background-color: #ffffff;
}
img.olPopup {
visibility: hidden;
}
I think because the Framed Cloud Pop-up border image div has no defined class of its own, I can’t hook into it like I did with img.olAlphaImg and img.olTileImage div to set the image borders to none.
Could someone please advise?
