(they’re deprecation notices, so they shouldn’t actually cause any breaking changes), and could you provide some more details, usually these warnings may come with some additional lines or a so called “stack trace” showing the commands calling each other leading up to the warning being issued like this. * It would also be nice to know what version of PHP you are on (you can find this information in the Tools > Site Health section, if you do not know it already). * Thread Starter [Yusup Ali](https://wordpress.org/support/users/fileour/) * (@fileour) * [3 years, 5 months ago](https://wordpress.org/support/topic/problem-after-update-wordpress-6-1/#post-16159168) * Thank you [@clorith](https://wordpress.org/support/users/clorith/) I have used PHP 8.1 * [marlinka](https://wordpress.org/support/users/marlinka/) * (@marlinka) * [3 years, 2 months ago](https://wordpress.org/support/topic/problem-after-update-wordpress-6-1/#post-16410269) * I have same problem if up php 7.4 on 8.0 or 8.1 wp version 6.1.1 .
