Hi,
I think you removed the parallax by the custom.theme.js file, did you? Please recover the custom.theme.js. There is a better way to forbid parallax in BM slider. There parallax function would zoom in the background image.
1./ 2. If you don’t want to use parallax, please follow:
– download the file, unzip it
– login FTP, go to wp-content ▸ themes ▸ theone ▸ functions ▸ theme ▸ plugins
– upload / replace ux-bmslider.php
3.
Please login wp-admin, go to Theone / General Settings / Custom Css
Paste the css to Custom Css:
body.page.has-ramp-separator #wrap{margin-top: -1px;}
.
