site diagnostic error

Hi there

Background updates do not work as expected
X The WP_AUTO_UPDATE_CORE constant is set and enabled.

The above error simply means there’s an issue with WordPress background update. Background updates ensures WordPress can auto-update and apply fixes to security issues, etc.

The issue can be caused by a plugin or theme conflict. You can try switching to any of the default WordPress themes to see if the issue exists. You can also try disabling all your plugins one after the other, while checking to see if the error disappears and which plugin was deactivated when it did.

Mismatched “post_max_size” and “upload_max_filesize” values.

As stated in the error, your post max size and upload nax file size are different.

If you’re using a Cpanel hosting, you’ll find the option to adjust this in “Select PHP version” or “MultiPHP INI editor” in your Cpanel dashboard. You’ll have to ensure that both options have the same value.

now my wordfence gives these messages:

Unknown file in WordPress core: wp-admin/includes/upgrade.php.orig

The above files aren’t core WordPress file and are likely malwares. You can delete them through your file browser or WordFence.

You should ensure you’re not using nulled themes or plugins as they’re the major source of this.

I hope this helps.

Cheers!

actually they are they original core wordpress files (.orig stands for original). These files are from a WordPress APS package used when you install WordPress via a management system like Plesk on a server rather than by installing manually. pretty harmless but also not needed to run the site after upload.

i also having same issue, I changed it in the PHP option but still same error as above.
Mismatched “post_max_size” and “upload_max_filesize” values.

thanks for the help/info it really helped me out tackling most of the issues

the issue with wordfence is now resolved it was indeed just deleteing it
after testing some plugins without succes i went looking for WP_AUTO_UPDATE_CORE on google for the issue with the update wordpress fell over the fact that
in the wp-config.php there was this line:
define(‘WP_AUTO_UPDATE_CORE’, ‘minor’); and i changed it to define(‘WP_AUTO_UPDATE_CORE’, true);
with seems to fixed the issue

the only thing im still haveing is the
“post_max_size” and “upload_max_filesize”
my host seems to have no option to manually change it
there is a option to select a php version but cant adjust the upload/post sizes
it does not have a option for that

they do have a infopage about the php versions and properties
with show their

post_max_size is 76 MB
and
upload_max_filesize 64 MB
i guess that issue is on their side
unless there is another trick to bypass it, i tried putting some php in .htacces
but that didn’t work i get the idea my host does not allow to change it.

anyways thanks for the tips and help most problems are resolved now

cheers!

>> define(‘WP_AUTO_UPDATE_CORE’, ‘minor’); and i changed it to define(‘WP_AUTO_UPDATE_CORE’, true); <<

FYI, that will be fixed in 5.5.1, whenever it comes out. ‘minor’ will again be a valid value.

Thanks for pointing that out. ??
