Stylesheet is missing
A common issue that can occur when installing WordPress themes is “The package could not be installed. The theme is missing the style.css stylesheet.” error message being displayed when uploading or activating the theme.
One of the reasons you may receive this error is if you have uploaded the incorrect file. You need to extract and locate the installable WordPress file from the full theme package.
Please make sure you are uploading only the installable theme which is called NameOf Theme.zip. If you upload ALL the files in the main package you will receive an error.
Upload the Installable WordPress file admin area
Log in to your WordPress admin area.
Browse to Appearance > Themes.
Click on ‘Add New’.
Click ‘Upload’.
Browse and select the theme zip file to ‘Upload’.
Upload Via FTP
WordPress files can also be uploaded manually via FTP.
Upload the files to /wp-content/themes/ folder on your server.
Login to your WordPress admin area to change the theme.
Syntax Error
If a syntax error or similar problems arise on your page during the theme or plugin installation, it is highly possible that the PHP version on your site is lower than the required version. You need to increase the PHP version on your Server at least to 5.6.
Demo Content isn't installing
If the installation process of the demo content isn't finishing after few minutes and showing the loading animation, or the front page of your website is still displaying a standard blog page even after importing a demo content successfully, You are suffering from PHP configuration limits that are set too low to complete the process. You should contact your hosting provider and ask them to increase those limits to a minimum as follows:
You can review the current Server limits under the Theme Name -> System Status section. If there is no such section in your theme, you can use this plugin - https://wordpress.org/plugins/debug-info/.
HTTP Error 500
In most cases, the cause of this kind of error during the theme installation is a low PHP Memory Limit on the Server. There are two methods of addressing memory limit issues:
Adjust yourself
Contact your hosting company
Do It Yourself
To adjust on your own, here are some methods to try. Be aware that this section requires advanced knowledge; it is not basic.
Edit your wp-config.php file
Add this to the top, before the line that says, “Happy Blogging”:
WordPress memory can be different from the server – you need to set this regardless of server memory settings
Here you can find an additional manual - https://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP.
Edit your PHP.ini file
If you have access to your PHP.ini file, change the line in PHP.ini. If your line shows 64M try 256M:
Edit your .htaccess file
If you don’t have access to PHP.ini try adding this to a .htaccess file:
Contact Your Host
Should you not feel comfortable in trying the above methods, or the above did not work for you, you need to talk to your hosting about having them increase your memory limit to 256M.
