Interworx allows users to override some of the common PHP values like:
upload_max_filesize = xxM
post_max_size = xxM
memory_limit = xxM
max_input_vars = x
max_execution_time = x
To override the values create a .user.ini file in your root directory.
Open with file manager in Siteworx, and add the values you want to change:
upload_max_filesize = 64M
post_max_size = 64M
emory_limit = 256M
max_input_vars = 5000
max_execution_time = 300
Next to make sure your value changes have taken place, create a info.php file in your root directory and add the following code:
Save this file, and browser to it https://example.com/info.php
This will display all your website PHP values.
