Can you check it please?

I watched the video and it is very weird that you don’t see the same issue. * I will check the environment and see if it could be related to the hosting configuration. * Thread Starter [Memo](https://wordpress.org/support/users/gtenaschuk/) * (@gtenaschuk) * [1 year, 12 months ago](https://wordpress.org/support/topic/fatal-error-on-wp-background-processing-library/#post-17807174) * Hey [@bsfherman](https://wordpress.org/support/users/bsfherman/) * You don’t see the issue because the zipwp tool creates the environment using PHP 7.4, my site is using PHP 8.2, and there is where i see the error. * I created a new site in my server using PHP 7.4 and it works. So, definitely the problem is in newer PHP versions. * Plugin Support [Herman Asrori (BSF)](https://wordpress.org/support/users/bsfherman/) * (@bsfherman) * [1 year, 11 months ago](https://wordpress.org/support/topic/fatal-error-on-wp-background-processing-library/#post-17813668) * Hi [@gtenaschuk](https://wordpress.org/support/users/gtenaschuk/), * I did another test and now is using PHP 8.2, however I still unable replicate the issue.

So i think that zipwp is creating environments with WP Cron disabled. * Can you check if zipwp has CRONs enabled, if not, if they have a way to enable CRON? or if you can try in another environment tool where you have CRONs enabled? * Thanks! * Plugin Support [Herman Asrori (BSF)](https://wordpress.org/support/users/bsfherman/) * (@bsfherman) * [1 year, 11 months ago](https://wordpress.org/support/topic/fatal-error-on-wp-background-processing-library/#post-17832513) * Hi [@gtenaschuk](https://wordpress.org/support/users/gtenaschuk/), * I just heard from our concerned team (FYI, ZipWP is part of us) that cron is not disabled on ZipWP. * Do you have another thought on this? * I look forward to hearing from you. * Kind regards, Herman 😊 * Thread Starter [Memo](https://wordpress.org/support/users/gtenaschuk/) * (@gtenaschuk) * [1 year, 11 months ago](https://wordpress.org/support/topic/fatal-error-on-wp-background-processing-library/#post-17837345) * Hey [@bsfherman](https://wordpress.org/support/users/bsfherman/) * Thanks for reviewing, i was trying to identify the issue so i went to create other tests in different hosting providers, below are the results. * I tested it in 2 more hosting providers, and in all of them i’m seeing the error, for example: 1.
