Not able to upload custom logo, images in colums and custom slides.

Hi,

I have installed mantra theme for 3 websites:-

https://www.demowebsite1.info/
https://www.demowebsite2.info/
https://www.demowebsite3.info/

I am unable to upload the custom logo, images in the columns and most important in the presentation page slider. I want to upload custom slides but don’t know why the images are not uploading. So I have to use featured images in the posts for the sliders.

Please help me resolve this concern.

If this can not be resolved please suggest me a way to make the slider images not clickable. As of now I am using the latest post’s featured images for the slider. But I do not prefer these slider images to lead to the posts page.

Looking forward to your reply.

Thanks a lot.

Best Regards,

Tarun
