Got error (Notice) in PHP 8.0.0

Thanks for your report. This plugin has not yet been tested in PHP 8.

I note that the PHP documentation has not yet been updated for spl_autoload_register with regard to this change in the function signature.

PHP 8.0.0 was released less than a week ago and WordPress should be considered Beta compatible so I don’t recommend you put it into production right now.

If my plugin works except for notices, then I suggest you suppress notices for the time being.

I will leave this ticket open to track PHP8 compatibility and aim to look at this soon.

Quick update to say that the spl_autoload_register error is fixed on the dev branch along with a couple of other PHP 8 fixes.

I’m not saying the plugin is PHP 8 ready yet, so there may be further errors. I expect it to be fully tested by the time I release version 2.4.7 which hopefully will coincide with the imminent release of WordPress 5.6.

Still an issue e.g. on /admin.php?page=loco-config&action=user

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.7
Current theme: Avada (version 7.3)
Current plugin: Loco Translate (version 2.5.2)
PHP version 8.0.2
