On the site I have Akeeba Backup + JCE Pro + Yoursites + D2 Content Pro. However, after disabling all non-core Plugins the error remains....

Ok. I'll test again with a clean Joomla 3.9.10 on another PHP 8 environment.

check your web hosts disable_functions value in php.ini configuration....

The @ error suppressor is "probably" masking that and because its a namespaced PHP file, the namespace is being prepended tot he function as a last resort then fatal erroring.

[PhilETaylor]

I have confirmed this tonight. The problem is that your webhost/you have disabled set_time_limit in your PHP Configuration (.user.ini, php.ini) files.

I tested with PHP 8.0.8 and:

disable_functions=set_time_limit

This is not a Joomla bug, only an insane webhost would disable PHP Core functions.

[pe7er]

Thank you both for your answers @brianteeman + @PhilETaylor set_time_limit had indeed been disabled. I've removed it from the disabled functions and the error has been gone.

stumped on same hoster issue with php 8.1 .. in akeeba following code is used to check for function if (function_exists('set_time_limit')) { set_time_limit(0); }

This should be reopened and fixed the same way

[sunnydrake]

also according to code this function is disabled in safe_mode

Its not 1990 any longer - any respectable web host would not be using safe_mode - there are very very little reasons now to run such a configuration.

http://php.adamharvey.name/manual/en/features.safe-mode.php

This feature has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

        if (function_exists('ini_get') && function_exists('set_time_limit'))
        {
            if (!ini_get('safe_mode'))
            {
                @set_time_limit(0);
            }
