If you are facing this error message
Fix Template Kit Install Error
There was an issue installing this template kit. Please try again.
Please upload a valid Template Kit zip file

Its related to your PHP config, check your Max Upload file size and Post Max Size , it should be more than the file size you trying to upload.

In some case memory limit shows this error, you can try by increasing memory limits too.

Set this settings to php.ini
upload_max_filesize = 256M
post_max_size = 256M
memory_limit = 512M
max_execution_time = 300
max_input_time = 300

If you dont have access to php.ini editor you can try adding it in .htaccess file , you can use wordpress file manager plugin if you don’t have server or ftp access.

Modify .htaccess
php_value upload_max_filesize 256M
php_value post_max_size 256M
php_value memory_limit 512M
php_value max_execution_time 300
php_value max_input_time 300

Save file.
