Fatal Erro

[koosang153]

After I upgraded my theme and cornerstone plugin and activate it, I see this error sign and my site looks broken, how can I fix it?
Following is the error code that poped up on the dashboard.

Fatal error: Uncaught Error: Call to undefined method ReflectionType::getName() in /4me22/www/wp-content/plugins/cornerstone/includes/classes/Util/IocContainer.php:55 Stack trace: #0 [internal function]: Themeco\Cornerstone\Util\IocContainer->Themeco\Cornerstone\Util{closure}(Object(ReflectionParameter)) #1 /4me22/www/wp-content/plugins/cornerstone/includes/classes/Util/IocContainer.php(63): array_map(Object(Closure), Array) #2 /4me22/www/wp-content/plugins/cornerstone/includes/classes/Plugin.php(111): Themeco\Cornerstone\Util\IocContainer->resolve(‘Themeco\Corners…’) #3 /4me22/www/wp-content/plugins/cornerstone/includes/classes/Plugin.php(100): Themeco\Cornerstone\Plugin->resolve(‘Themeco\Corners…’) #4 /4me22/www/wp-content/plugins/cornerstone/includes/classes/Plugin.php(66): Themeco\Cornerstone\Plugin->setup_services(‘preinit’) #5 /4me22/www/wp-content/plugins/cornerstone/includes/boot.php(21): Themeco\Cornerstone\Plugin->initialize(Array) #6 /4me22/www/wp-content/plugins/cornerstone/cornerstone.php(20): cornerst in /4me22/www/wp-content/plugins/cornerstone/includes/classes/Util/IocContainer.php on line 55

Hi @koosang153,

Thanks for reaching out.
It seems the PHP version is the reason behind your issue, I would suggest you upgrade the PHP version to 7.4 by contacting your Hosting Service provider and checking if that issue resolves or not.
If that issue does not resolve after you update the PHP version, please copy your live site to a staging server so we could troubleshoot freely without breaking your live site.
And give us access in the secure note including:

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

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

Thanks
