Maximum Execution Time (max_execution_time) 0 only solution is change the theme

Question

My Maximum Execution Time never changes. I don't have a php.ini file but I changed the values in my server. The other WordPress sites on the same server are fine but this site is giving me issues. The only way it works is if I change the theme to a default one. If the theme is the issue I don't understand why it continues even after a fresh install of the theme. WordPress is showing a Memory Limit of 256M but under PHP max limit it is showing 0

Version 7.2.15 
Memory Limit (memory_limit) 256M
Maximum Execution Time (max_execution_time) 0
Maximum File Upload Size (upload_max_filesize)  64M
Maximum File Uploads (max_file_uploads) 20
Maximum Post Size (post_max_size)   128M
Maximum Input Variables (max_input_vars)    10000

Steps I have taken:

Reinstall theme Reinstall WordPress Update Server with the latest software Disabled all plugins

Added this to my Wpconfig.php : under this /**#@-*/

/** Memory Limits. */
define('WP_MEMORY_LIMIT', '256M');
define('WP_MAX_MEMORY_LIMIT', '256M');
/**

Created .user.ini file with these values:

upload_max_filesize = 64M
post_max_size = 128M
memory_limit = 128M
max_execution_time = 600
max_input_vars = 10000
max_input_time = 400

The only reason I figured this out is because im using gravity forms and the form kept crashing when I submit it.
