Hi,
For the first site, try this custom CSS, it will add more responsiveness:
[html]@media only screen and (max-width: 720px) {
.rpp_item {
width: 33% !important;
}
}
@media only screen and (max-width: 520px) {
.rpp_item {
width: 50% !important;
}
}
@media only screen and (max-width: 360px) {
.rpp_item {
width: 100% !important;
}
}[/html]
On the second site, on the Advanced Options panel, on ‘the exclude posts by ids’ option, there was an extra comma after the end of the list, which caused the problem. I have removed it, now it should be fine.
