after a lot of thinking, I've decided to import my standalone websites into wordpress network using backupbuddy. Everything went quick and smooth, posts, pages, theme settings, logo... everything is perfect - except images in the slider :(
You can see one of this websites over here:
Slider show icons for broken images, and when you actually right click that broken image and click open image in new tab, you will get something like this:
So, basically something is adding website url before an image url and that makes it broken.
When I go to widget settings(this theme add slider images through widgets), everything looks good - correct url etc.
Any thoughts ?
