That doesn’t sound like a good idea for a few reasons.

-Speed problem: Your visitors will have to download both themes if they visit both themes. This is not good for either of your bandwidth.

-Maintenance: You now have 2 code bases. They are both written differently and you will eventually have to learn both code bases if you plan to do anything.

Compatibility issues: You will need to make sure both themes work with a plugin instead of 1 theme. You will have to do double the testing.

However, if you’re really into it, there’s two ways to accomplish it.

1- Using a plugin, despite isn’t possible to determine how the result will look like: https://www.ads-software.com/plugins/jonradio-multiple-themes/

2- Manually merging the themes like copying css, headers, etc.

It’s advisable to keep things default, otherwise you could damage the theme layout by eliminating those generated resized images.

However, if you want to take the risks and proceed with this operation you can refer to this topic, it is shown in the last reply how to:

Are you sure you’re running the 4.9 WordPress version?

This is a common error for plugin conflict and old versions problems.
Since you haven’t installed any plugin yet this could be the second alternative.

Some themes implements functionalities that requires specific features from new WordPress versions, so when you try to run those themes with an old WordPress version that blank page appears.

Please let me know if it isn’t the case, so we can continue to look for this problem source.

For what I know this is not a default WordPress pattern.
Like you said this comportment could have been caused by some plugin.
Also some themes implements this type of verification to secure the Website against possible server hacking.
You should check your functions.php file to see if there’s anything there causing this action.

Please let me know if this tutorial will help you:

https://www.wpbeginner.com/wp-themes/how-to-use-multiple-themes-for-pages-in-wordpress/

This is possibly being caused by a plugin conflict.

The following tutorial teaches you how to check which one is it.

Please, try to follow these steps and tell me how it goes.

Add the following to the additional css inside the theme customization:

.current_page_item a {
color:red!important;
background:black!important;
}

Mix the text and bg colors using hex values until you got it the way you want it.

I think this plugin has what you’re looking for:

Here’s how to customize it:

I like to use this one for this type of job:

https://www.ads-software.com/plugins/wp-responsive-recent-post-slider/

It depends on the theme to have or not support to each one of the posts format. You can add them manually, but probably the result won’t look good.

In this codex tutorial they explain in a very detailed way how the post format works and how to add any of them manually by changing the functions.php file.

Please give a look at: https://codex.www.ads-software.com/Post_Formats

Do you want to order it manually, like dragging and dropping in the order you want them to appear?
If that’s so use this plugin to do the job:

https://www.ads-software.com/plugins/simple-custom-post-order/

Please let me know how it goes.

Wordpress Codex recommends these two plugins for multisite domain rename:

1- https://www.ads-software.com/plugins/velvet-blues-update-urls/
2- https://www.ads-software.com/plugins/better-search-replace/

Please, try those and tell me how it goes.

Here is a very complete and intuitive tutorial to sync the users between two blogs.

Please follow those steps and let me know if this permission error persists.

Would you please test if one of the follow CSS code would do the trick? (apply it in the Quick CSS present in the Theme customization)

? First attempt:

@media (max-width: 767px) {
aside.sidebar {
display: block!important;
}
}

? Second attempt:

@media (max-width: 767px) {
.sidebar {display:block !important; clear: both; }
}

Some custom wordpress theme doesn’t show the admin bar into the theme page same with the wp_head() and the wp_footer() wrote on the templates files. To resolve that problem just add the following code into your function.php or into your own plugin:

function admin_bar(){

if(is_user_logged_in()){
add_filter( ‘show_admin_bar’, ‘__return_true’ , 1000 );
}
}
add_action(‘init’, ‘admin_bar’ );
