Hi,
Your header is transparent the gray that you see is from the top color section on the page:

when the header is scrolled the #897270 color is from your Logo Area Color:

if you don’t want a transparent header change the setting on the page in the backend in the admin sidebar:

As for the header widget, I disabled the above css and added this:

@media only screen and (min-width: 990px) and (max-width: 1670px) { 
	#header_main .inner-container .widget .textwidget {
  	 margin-left: -196%;
  }
}
@media only screen and (min-width: 990px) and (max-width: 1440px) { 
  #header_main .inner-container .widget .textwidget p span {
  	 font-size: 14px !important;
  }
}
@media only screen and (min-width: 1441px) and (max-width: 1670px) { 
  #header_main .inner-container .widget .textwidget p span {
  	 font-size: 18px !important;
  }
}
  #header_main .inner-container {
  display: flex; 
  flex-wrap: wrap; 
  justify-content: center;
  align-content: center;
  }
  #header_main .inner-container .widget {
  	padding: 0;
  }
  #header_main .inner-container .widget .textwidget {
    align-content: center;
    height: 100%;
  }

Hi,
To change the color of the burger menu icon on desktop try this CSS in your Enfold Theme Options ▸ General Styling ▸ Quick CSS field:

#top .av-burger-overlay li li .avia-bullet, #top .av-hamburger-inner,#top .av-hamburger-inner::before, #top .av-hamburger-inner::after {

To adjust the width of the mobile menu go to Enfold Theme Options ▸ Main Menu ▸ Burger/Mobile Menu Styling ▸ Flyout Width

Hi,
If you just want to show different widgets in the footer for different pages, I recommend using the plugin Widget Options, it offers a easy way to choose which widgets show on each page.

Hi,
I recommend creating different widgets in your footer and use the plugin Widget Options to show each widget on specific pages and then use css like above to hide the footer on all other pages.

Mike

Hi,
This assumes that you want the footer to show only on this page at screen sizes over 1440px, feel free to adjust to a different screen size if you wish.
Try this CSS in your Enfold Theme Options ▸ General Styling ▸ Quick CSS field:

@media only screen and (min-width: 1440px) { 
#top:not(.page-id-3288) #footer {
	display: none;
}
}
@media only screen and (max-width: 1439px) { 
#top #footer {
	display: none;
}
}

After applying the css, please clear your browser cache and check.

Hi,
Most of your errors seem to be coming from the WordPress core file /wp-admin/includes/template.php, I’m not sure why this is, but I recommend starting over and use the plugin instead of trying to do it yourself manually.
I don’t recommend trying to use the plugin to overwrite your current errors, delete your current new WordPress install and start over.
Another option may be to use your webhost staging site option, most cPanel webhosts have a staging site option, some in the dashboard:

Others add the option in the Softaculous WordPress Management

There may be other staging site options in different cPanel servers, these are the two that I have seen.

Mike

Hey Chancenzeit,
When I check your homepage the text editor opens and saves correctly:

perhaps a screenshot of your trouble would help.
