Pro Update from 4.2.3 to 4.3.3 Crashes WP Dashboard

[twv0001]

Receive the following error when updating Pro from 4.2.3 to 4.3.3:

Fatal error : Uncaught Error: Call to undefined method ReflectionType::getName() in /home/customer/www/staging2.kayamping.net/public_html/wp-content/themes/pro/cornerstone/includes/classes/Plugin.php:106 Stack trace: #0 [internal function]: Themeco\Cornerstone\Plugin->Themeco\Cornerstone{closure}(Object(ReflectionParameter)) #1 /home/customer/www/staging2.kayamping.net/public_html/wp-content/themes/pro/cornerstone/includes/classes/Plugin.php(117): array_map(Object(Closure), Array) #2 /home/customer/www/staging2.kayamping.net/public_html/wp-content/themes/pro/cornerstone/includes/classes/Plugin.php(137): Themeco\Cornerstone\Plugin->create(’\Themeco\Corner…’) #3 /home/customer/www/staging2.kayamping.net/public_html/wp-content/themes/pro/cornerstone/includes/classes/Plugin.php(73): Themeco\Cornerstone\Plugin->resolve(’\Themeco\Corner…’) #4 /home/customer/www/staging2.kayamping.net/public_html/wp-content/themes/pro/cornerstone/includes/classes/Plugin.php(44): Themeco\Cornerstone\Plugin->setup_services(‘is_admin’) #5 / in /home/customer/www/staging2.kayamping.net/public_html/wp-content/themes/pro/cornerstone/includes/classes/Plugin.php on line 106

What I have already tried:
Deactivating all plug-ins and updating
Deleting child theme and using Pro only
Deleting both Child and Pro, activating a standard WP theme, then re-installing 4.3.3 fresh and activating

Switching to a standard WP theme is the only thing I have found to alleviate the issue.

Hi @twv0001,

Thanks for reaching out.
I would suggest you deactivate and delete the Pro and re-install the latest version i.e 4.3.3 by downloading from your Themeco account and check if that resolves your issue. If that does not help, please provide login credentials for your site in a secure note to examine it further, including:

– WordPress Site URL & Login URL
– WordPress Admin username/password
– FTP/CPanel to access the files

To create a secure note, click the key icon underneath any of your posts.

NOTE: The URL is protected with HTTP authentication and the given credentials are not correct for that.

Thanks

Hello @twv0001,

Regretfully the given WP Authentication and the WP login details do not work for us. Can you please double-check again so we can log in?

Thank you.

Apologies on that!

This should work:

Hello @twv0001,

Please go to Tools > Site Health > Information > Server. Your PHP version is 7.0. You need to update it to 7.4.

You may need further assistance from your hosting provider to be able to update your PHP version.

Best Regards.
