To run Vehica your host should support PHP Version 7.4 or greater. PHP settings:

• upload_max_filesize = 8M
• post_max_size = 8M
• max_input_time=300
• max_execution_time=300
• memory_limit = 196M

You can modify your server settings in the cPanel or in the php.ini file if default limits are too low. If you cannot modify it by yourself, please contact your hosting provider and send this minimum requirement so they can change it for you.
