First of all you need to check LEVELUP theme requirements before you start the installation process on your server:
WordPress 3.1 or higher
PHP 5.4 or higher
MySQL 5 or higher
Also your server must meet the following recommended PHP configuration limits:
upload_max_filesize 32M
post_max_size 32M
max_execution_time 180
memory_limit 128M
max_input_vars 5000
Using cheap hosting you may face the errors such as demo content import failure, blank screen, issues with page builder etc. The reason may be the PHP configuration limits are set to lower values than listed above. To solve this you need increase PHP limits on your server, you can do it yourself if possible or ask your hosting provider to help you set these limits to appropriate values.
