Hi LabTintas
The cause maybe by your hosting. Please contact to your host provider, they will check or changes some values. Here are some requirements For KuteShop:
Before you begin the install, checking to ensure that you have the minimum requirements for Kuteshop is WordPress 4.4.0 or highter, PHP 5.4 or highter and MySQL 5.4 or highter.
Recommended PHP Configuration Limits.
Many issues that you may run into such as; white screen, demo content fails when importing, empty page content with Fusion Builder and other similar issues are all related to low PHP configuration limits. The solution is to increase the PHP limits. You can do this on your own, or contact your web host and ask them to increase those limits to a minimum as follows:
max_execution_time 300
memory_limit 256 M
post_max_size 64M
upload_max_filesize 64M
Please check and re-install your theme. Or please provide your Cpanel + admin login accounts details via secret information area . I would like to check your host and install for you.
Regards,
Note: Please let me know, which option number do you want?
