# How to adjust max_vars_input on Plesk Windows

To adjust the `max_input_vars` setting on **Plesk for Windows**, you need to modify the PHP configuration for the server or for individual domains. The `max_input_vars` setting limits the number of input variables that can be handled in a single PHP request, and it's commonly adjusted to accommodate large forms or data submissions.

You may not see an option to set the value for a specific domain, thus thus we will guide on how to set the value globally on the server.

**Log into Plesk**:

- Log into Plesk as an administrator.

**Navigate to Tools & Settings**:

- In the Plesk dashboard, go to **"Tools & Settings"** under the **"Server Management"** section.

**Select the PHP Version**:

- Choose the PHP version you want to adjust (Plesk may have multiple PHP versions installed).
- Click **"View the php.ini file"** next to the PHP version you want to modify.

**Edit the php.ini File**:

- Look for the `max_input_vars` directive in the `php.ini` file, and uncomment it by remocing the preceding **semi colon** then give it a value that you desire, e.g 5000
- If it’s not already present, add the following line: `max_input_vars = 3000`
  - You can replace `3000` with the desired value.
