Hello. Thank you for contacting the Toolset support.
As of now, this is known to us are we are working on to make Toolset plugins fully compatible with PHP 8. Maybe you can find the PHP 8 compatibility will be added with the next release but we do not have any ETA on it.
I suggest for now, you should go with PHP 7.x.x and keep using it until we officially publish the PHP 8 compatibility with Toolset plugins.
My server is close to PHP 7. x.x and the Server is recommended to use PHP 8.0. SO I need to fix this issue as soon as possible and please provide an estimated time for PHP 8 compatibility.
The second option is temporary you will fix your plugins issue on my website.
We are working hard to make Toolset fully compatible with PHP 8 and our Devs are already on it.
Its really risky move of your hosting authority to not offer PHP 7 as we do not have any other option to offer at the moment. You may would like to request your hosting authority to offer you PHP 7 so at least you can continue your work as we can not have any control on it.
Maybe you can continue your development on your localhost and then update to server when Toolset plugins fully compatible with PHP 8. I know this is not the solution you would like but this is fact and you will require to take nest steps accordingly. Maybe you can see we will release PHP 8 compatibility in 2-4 weeks from now but please note that there is no ETA on it. Our developers are working hard to make it possible.
