PHP version (7.4.33) is no longer supported

Hey MaskiMichener,
Thanks for the login, I see that you are using a child theme with many custom files, I suspect that some of these files are from an older version that didn’t support PHP v8, such as your header.php, for example.
Try enabling the parent theme and then enable PHP v8, if you still get an error it could be one of your plugins, try disabling all of your plugins then enable PHP v8 and enable your plugins one at a time until you find the error.
Enfold v5.4.1 does work with PHP v8.

Best regards,
Mike

Hi,
Can you tell us what the fatal error message is? That would help. Try enabling wp_debug with the following code, inserted in your wp-config.php file via ftp:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );

and then a debug log should be created.

Best regards,
Mike

Hi,
Thanks but the error There has been a critical error on this website. doesn’t tell us anything helpful.
Please switch back to V7.4.33, disable all plugins, enable WP_DEBUG in the wp-config.php file via ftp, and then switch back to PHP v8, hopefully the WP_DEBUG_LOG will catch the error.
Sorry for so many steps.
Please include FTP access in the Private Content area so we can see the WP_DEBUG_LOG and know which child theme file is causing the error.

Best regards,
Mike

Hi,
Thanks for trying but the WordPress ▸ Dashboard ▸ Tools ▸ Site Health ▸ WordPress Constants say debug is disabled:

I tried to login to your GoDaddy host but it requires 2-stage authorization, can you disable this?
If so we should be able to access the FTP & the PHP settings from there, If not can you post FTP access for us in the Private Content area so we can enable wp_debug before you switch over to PHP v8?

Best regards,
Mike

Hi,
With the WP_DEBUG active I could see these errors:

Notice: Undefined index: id in /var/www/wp-content/themes/enfold-child/functions.php on line 145
Notice: Undefined index: id in /var/www/wp-content/themes/enfold-child/functions.php on line 145
Notice: Undefined index: featured in /var/www/wp-content/themes/enfold/functions.php on line 313
Notice: Trying to access array offset on value of type null in /var/www/wp-content/themes/enfold/functions.php on line 313

Warning: Illegal string offset 'js' in /var/www/wp-content/themes/enfold/includes/helper-assets.php on line 61

and I was able to disable the custom code in your child theme functions.php that caused the errors, but since I didn’t have FTP assess I was limited to what I could do.
I don’t know what the reason for of some of these custom functions was so I don’t think that I will be able to modify them, I get the feeling that you had hired a freelancer to create these customizations for you and the core theme files have changed since then so these modifications will also need to be changed.
Perhaps you should contact this freelancer again for assistance.

Best regards,
Mike

Hi,
Thanks for the Invitation, I received the email and clicked it, but when I tried the login info above it said your email was used for the 2-factor and not mine, perhaps my email requires a different login than the one posted above, please check.
Do you know what version of the theme was used when your website designer created the custom elements in the child theme?

Best regards,
Mike

Hi,
I was able to login to Godaddy and I see now that the site is using PHP v8 with the child theme and the plugins are enabled, and I don’t see any obvious errors on the frontend so it seems that disabling the custom code in the child theme functions.php has worked.
Please clear your browser cache and check.

Best regards,
Mike
