Title: Plugin causing Site Health Errors: An active PHP session was detected Last modified: May 5, 2022 --- # Plugin causing Site Health Errors: An active PHP session was detected * [olessol](https://wordpress.org/support/users/olessol/) * (@olessol) * [4 years, 1 month ago](https://wordpress.org/support/topic/plugin-causing-site-health-errors-an-active-php-session-was-detected/) * The plugin causes 1 critical issue: **A PHP session was created by a session_start() function call. This interferes with REST API and loopback requests. The session should be closed by session_write_close() before making any HTTP requests.** * I had to disable the plugin. * Version 1.1.9 Viewing 9 replies - 1 through 9 (of 9 total) * Plugin Support [Mark Kevin](https://wordpress.org/support/users/mkesteban08/) * (@mkesteban08) * [4 years, 1 month ago](https://wordpress.org/support/topic/plugin-causing-site-health-errors-an-active-php-session-was-detected/#post-15621005) * Hi [@olessol](https://wordpress.org/support/users/olessol/) , * It could be a conflict with another plugin or even with the theme. Could you please try to re-activate the Premmerce plugin, and proceed in deactivating the other plugins on your site and see if the issue will persist. * Please feel free to let us know how it goes and I’ll be glad to further assist you with this. * [sxmotive](https://wordpress.org/support/users/sxmotive/) * (@sxmotive) * [4 years ago](https://wordpress.org/support/topic/plugin-causing-site-health-errors-an-active-php-session-was-detected/#post-15651783) * I have the same issue. * `A PHP session was created by a session_start() function call. This interferes with REST API and loopback requests. The session should be closed by session_write_close() before making any HTTP requests.` * I disabled all plugins (except WooCommerce and Premmerce Wholesale Pricing for WooCommerce) and have changed theme to default.
