The demo is imported and you can continue replacing the dummy text/images with your content. There are no problems working with it. I logged in and changed the background image of the first slide of Codeless Slider that is in home page. I had no issues with it. See screenshot of customizer: https://ibb.co/92gGy3v
No errors showing. Also there are no errors or warnings showing in the admin panels either: https://ibb.co/nQ2CLqy
Note:warnings do not affect your work. It is good to let us know if you are getting any so we can check but a warning will not stop you from using the option panel or making changes to the site.
The space is caused by some text generated. See screenshot: https://ibb.co/Fs6TH1M
Did you add any new plugin lately? Or added any new script? I suggest you deactivate all third party plugins and try again.
The smooth scroll is indeed a functionality included in theme for the one page layout. You can set it up in General Options > Smooth Scroll.
The page you have the links to sections, need to be set up as a one page in order for the smooth scroll to have effect.
Add two rows:
1-in the first add the slider to show in desktop; check the option to make it invisible in mobile (screenshot: https://postimg.cc/YGvDfT7T);
2-in second row, add the slider to show in mobile. The same, check the options to hide it in desktop.
Let me know if you have questions.
I recommend you to install the Jetpack plugin that is free and offer a free cdn service.
The only slow speed of the website is caused by the size of the images.
The images size need to be lower than 100kb. Some of the images above are more than 1MB.
I recommend you also to install w3total cache plugin.
Sorry but it’s not possible to add slider to posts.
-To re-position the text in the gray bar after changing the width, change the “margin-left:” value as well. Increase/decrease it until you are satisfied with the result.
What theme version are you running? What wordpress version? Please make sure to have the latest theme version and then update all it’s included plugins.
If the situation persists, send us some wp credentials in a private reply. So we can give it a closer look.
The demo imported is indeed “Scroll story”. The dummy data of it is extracted from the same demo you send us. Perhaps the first background image is not the same, but the demo it is. Change the background image by going to the Row settings > Design > Background Image. Import another image here.
