Because PHP version 7.2 is no longer supported and as all my webpages are written using Site Designer, I am not sure how to see what version Site designer is written in.
I tried changing one of the sites, but it automatically had a message that the site had moved.
In Page Manager there are only 2 categories for PHP (PHP & PHP 3).
We are now on version 8 or 8.2.
I know some of the content I had to alter so I am not sure whether that is where the error is.
I have changed it back to version 7.2, until I can change the code.
Can anyone give me advice on how to change the code to be compatible with the new version?

Hi Rocky,
Site Designer has no issues with php as any php in SD would be put there by you. Looking at the error.log on your host will point you in the direction of what needs to be fixed in your scripts.
If you can share that it would be great.
