Hello @stasfalkovich,
I am another staff checking on the thread. If you check our documentation and also the WordPress requirement’s page, you have this:
**Note**: If you are in a legacy environment where you only have older PHP or MySQL versions, WordPress also works with PHP 5.6.20+ and MySQL 5.0+, but **these versions have reached official End Of Life** and as such may expose your site to security vulnerabilities.
The WordPress documentation itself clearly states that the recommended PHP version is 7.4. Though this is just documentation, it is best to follow those recommendations to avoid issues.
In some cases, a fatal error during the updates can be caused by a broken PHP code or duplicate function name which were added in your child theme’s functions.php file. If you can give me access to your site, I would love to personally investigate this critical error. You can create a secure note in your next reply with the following info:
– Link to your site
– WP login URL
– WP username
– WP password
– WP Administrator Role
- Confirmation that we can access and make changes to your site
To know how to create a secure note, please check this out: How The Forum Works
In the meantime, please enable your debug mode. You can do this by opening wp-config.php
file and adding:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define( 'WP_DEBUG_DISPLAY', true );
/* That's all, stop editing! Happy blogging. */
When you revisit the page, you should have some error output describing the issue in more detail. If you are getting a message that it encounters a critical error and asks you to check your admin email, you can always go and check the debug.log in your wp-content
folder.
And by the way, please do check the Tools > Site Health > Status. Make sure that there are no Performance issues because, sometimes, they cause critical issues as well.
Thank you in advance.
