Title: Subscriptions doesn’t work for PHP 8.x Last modified: October 31, 2022 --- # Subscriptions doesn’t work for PHP 8.x * Resolved [rogerkullang](https://wordpress.org/support/users/rogerkullang/) * (@rogerkullang) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/) * My web-hotell will soon switch over to PHP 8.0 (from 7.4) and I have discovered that the plug-in will not send subscription emails with a PHP version greater than 8.0 (tested with both 8.0 and 8.1). * When I manually trigger sending e-mails to subscribers I get an error message, so it should be pretty easy to reproduce. * Since my users are heavily relying on the subscription feature, it would be good if this could be solved asap.

I will however upgrade my xampp test environment to test with the latest PHP * Kind Regards, Sidney - This reply was modified 3 years, 7 months ago by [vandestouwe](https://wordpress.org/support/users/vandestouwe/). - This reply was modified 3 years, 7 months ago by [vandestouwe](https://wordpress.org/support/users/vandestouwe/). * Thread Starter [rogerkullang](https://wordpress.org/support/users/rogerkullang/) * (@rogerkullang) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/#post-16173170) * Thanks [@vandestouwe](https://wordpress.org/support/users/vandestouwe/) for replying on my issue. I installed the “WP Mail Log” plugin as advised in the user manual. Is that what you referred to as a sendmail plugin or am I missing another plugin? * I tried to upgrade to PHP 8.0 again, and when doing force_run got “Code: undentified Exception: undentified” * When checking the “WP Mail Log” there is nothing in the log so apparently an exception is triggered before any mail is sent out. Any empty $_GET() statements that aren’t handled? - This reply was modified 3 years, 7 months ago by [rogerkullang](https://wordpress.org/support/users/rogerkullang/). * Plugin Author [vandestouwe](https://wordpress.org/support/users/vandestouwe/) * (@vandestouwe) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/#post-16173440) * Now also tested with PHP version 8.1.10 nut as sted before It is advised to you a sendmail provider to takeover the PHP sendmailfunction * Plugin Author [vandestouwe](https://wordpress.org/support/users/vandestouwe/) * (@vandestouwe) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/#post-16173614) * No you need to add a plugin that takeover the wp_mail function from PHP. Use the one I suggested in the manual * Thread Starter [rogerkullang](https://wordpress.org/support/users/rogerkullang/) * (@rogerkullang) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/#post-16176366) * Many thanks for trying to help me with my website issues! * The manual doesn’t actually mention anything about the wp_mail SMTP function. I read the full 33 pages and not in a single sentence is this mentioned. I did however see a snapshot of how you have configured your add-ins on page 9 and was able to find WP Mail SMTP and configure it. You might want to update the manual on this topic OR I am reading the wrong version? 2.6.12 is the latest on the addin page. * Unfortunately, even with WP Mail SMTP properly setup, I still get the error as mentioned before (the exception from force_run). I also cannot see any mails going out from the mail log (which works for the WP Mail SMTP test e-mails). Do I need to re-initialize the “Subscribe to category” WP-addin? * Plugin Author [vandestouwe](https://wordpress.org/support/users/vandestouwe/) * (@vandestouwe) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/#post-16176412) * Can you please check if the mails go out based on the cron timer.

Are you sure your provider supports php 8. It looks to me that they dont. * Thread Starter [rogerkullang](https://wordpress.org/support/users/rogerkullang/) * (@rogerkullang) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/#post-16186986) * I am certain that I am using the correct version of PHP since I can control which version I am using from a control panel that one.com has implemented. I also check which version the site is using with the phpinfo() call. They support 8.0.25 and I have also tried 8.1.12 with the same result. * I can see that the error log path is not set to a value and I am checking with my host provider to see if it is possible to retrieve the log somehow. * Plugin Author [vandestouwe](https://wordpress.org/support/users/vandestouwe/) * (@vandestouwe) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/#post-16187042) * Please load version 2.7.3 I do not think it will solve yur problem but then you are least up to speed * Thread Starter [rogerkullang](https://wordpress.org/support/users/rogerkullang/) * (@rogerkullang) * [3 years, 7 months ago](https://wordpress.org/support/topic/subscriptions-doesnt-work-for-php-8-x/#post-16188561) * Success! It tried with disabling the plug-in and re-enabled it again. Now the timer function work again with PHP 8.1.12 (and version 2.7.3 of the plug-in). Haven’t tried the manual trigger function, but the problem from my point of view is resolved. * Don’t know why I didn’t think of that, maybe something that could be added to a troubleshooting section in the manual (unless it isn’t there already). * Many thanks for your assistance in this thread!
