====== Plesk Mismatched PHP Configuration ======

In certain cases you may see that a PHP setting in the panel is not corresponding with the one you see on the phpinfo page. Typically this can happen with **upload_max_filesize** and **post_max_size**. 

In this example, **upload_max_filesize** is set to ''128M'' and **post_max_size** is set to ''128M'', but phpinfo shows ''2M'' and ''8M'', respectively.

Also, the PHP version may not match the one you set in PHP settings. For example, the panel's PHP version is set to ''7.3.5'', but phpinfo shows ''7.2.18''.

===== How to Fix the Issue =====

LiteSpeed on Plesk requires the PHP handler to be set to ''FastCGI application''. When it is set to ''FPM application'', it may result in an inability to apply PHP settings. Setting the handler to FastCGI does not mean lower PHP performance when compared to PHP-FPM. LiteSpeed will load PHP with its own seamless, optimized LiteSpeed SAPI.

Log in to Plesk, navigate to the website's **PHP settings** page, set **run PHP as** to ''FastCGI application'', and save.

Now check the phpinfo page again. The values should now match.

**NOTE** As of LSWS v5.3, with the introduction of PHP Detached Mode (which is the default), the application of the new configuration may be delayed. A new configuration only takes effect once lsphp is restarted. You will either need to wait for the lsphp process to time out and fork again, or you can manually kill it.

==== What if FastCGI is Not an Option? ====
If the FastCGI option is not shown, it may have been disabled.

Navigate to **Tools & Settings > PHP Settings**.

Click the grey dot in front of the handler to enable it.
