I’m trying to turn off breadcrumbs on mobile. When I go to Theme Options > Header > toggle Breadcrumbs to “off,” it not only doesn’t work, but if I go to check on it again, it will be turned back on.
Please try increasing the memory limit in case theme options panel is not working properly. You can take a look at following resource for some help:
Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
You also have the option of using following CSS under X > Theme Options > CSS:
.x-breadcrumb-wrap {
display: none;
}
