    This message displays when I select Notify Users about this Post in a post:

    Warning: The number of users (42) plus overhead exceeds the PHP max_input_vars setting (0). You will not be able to send email to more than -10 users in one batch. This can be changed by increasing the value of max_input_vars setting in the PHP.ini configuration file.

    I’ve searched for a php.ini in all files in my Website, and there are no search results. Where can I find this file so I can change max_input_vars?

    The PHP.ini file is usually a server file and not one you can change unless you manage your own server. On Windows servers it is commonly located at C:\PHP\php.ini. On Unix/Linux servers it could be almost anywhere. If you are on a shared hosting plan it is unlikely you have the ability to edit the PHP.ini file.

    That said, I am not sure what a value of 0 will do.

    Here is an SO thread that has some additional information including a note that MAX_INPUT_VARS cannot be set with ini_set().

    Mike: I don’t manage my own server, so I’ve had no recourse but to uninstall “Email Users” and set my users up in both WordPress and gmail. Just one more step, annoying because I have so many users who have to be set up, but workable. Thanks for the information you sent me.

    Did you actually try to send the email even with the warning? I am curious what a value of 0 would do. Sending to 42 users should not be an issue for just about any hosting plan.

    Mike, no I didn’t try to send the email with the warning. I couldn’t take the time to also send personal emails to everybody on the list asking if they received the email and then follow up on all the responses from them.
