2. Some images are missing

4. Does the theme support custom fonts? Can I use my own font?

5. How to update the theme?

The admin notice "Unyson: Your website is hosted using the LiteSpeed web server. Please consult this article if you have problems backing up." indicates that your web hosting company uses the LiteSpeed web server. It seems that LiteSpeed encounters issues with all WordPress scheduled tasks that extend beyond a very short duration, including backup plugins.

You need to make changes to the files .htaccess and wp-config.php located in the root folder of your website:

1) .htaccess  - add this line at the bottom:

RewriteRule .* - [E=noabort:1]

2) wp-config.php  - add these values or replace old ones (if they are already exist):

define('DISABLE_WP_CRON', true); 

define('ALTERNATE_WP_CRON', true);

Issues:

• Cannot redeclare wp_cache_add() ...
• Maximum execution time ...
• Some images are missing.

Solution:

Or after installation, you notice that some images are missing, you do not need to reinstall the demo content after this error. Here is a guide to fix this problem.

https://wordpress.org/plugins/regenerate-thumbnails/

2. In the Tools menu, the entry "image regeneration" will appear:

3. Click on the button marked on the screenshot:

At the end of the image regeneration process, thumbnails for all images will be restored.

This is the known problem with cache, so to fix it follow this: 

1. Go to Essential Addons => Tools, click on Regenerate Assets button

2. Go to Elementor => Tools, click on Regenerate Files & Data button

3. If you have any other plugin for caching so clear that cache also

Yes, you can choose any in Elementor Global settings to set globally or change only on a specific demo.

Just install the new version as regular theme (without demo installation). Feel free to ask for support if it’s not clear!
