Fatal error on website

[l_eckardt]

Hello there,

we have a Fatal Error on our website. I don’t know where it comes from, we haven’t made any big changes.
This is the displayd code :
Fatal error: Cannot declare class Cornerstone_Header, because the name is already in use in /homepages/9/d788453068/htdocs/dev/wp-content/themes/pro/cornerstone/includes/classes/regions/class-header.php on line 3

We also contacted our programmer but he couldnt finde anything. The error is in the theme code.
Can you please provide us with an answer as soon as possible?

Thanks

Hi @l_eckardt,

Thanks for reaching out.
There might be a few different reasons behind your issue. First of all please check if the Cornerstone is already installed as a separate plugin, if so please deactivate and delete before check. If that is not the case please deactivate and delete the Pro and re-install it by downloading from the Themeco account.

The PHP version can be another reason behind your issue, I would suggest you upgrade the PHP version to 7.4 by contacting your Hosting Service provide and check if that issue resolves or not.

Hope it helps.
Thanks
