Error displaying on main page

[Square Wheels]

I upgraded to the current version, including the patch yesterday.  Now I see this error most times when I load the front page.  Is there a way to see what app is causing it?  I know I could turn them all off then turn them on one at a time, but the error doesn't display all the time.

Thanks

Its a problem with PHP8

That appears to be related to this issue:

 

This is something which our team is investigating in relation to PHP 8.

Reverting to PHP 7.4 may fix the problem for you, until we find the underlying cause.

Ugh, thanks.  I hope this is fixed soon as I am on the current release, so I cannot go backwards, and my support runs out in a few days.

I thought 4.7.1 required 8?  I suspect I am wrong.

If I leave it at 8, is it going to cause any issues other than loading up the error log?

Thanks

Minimum is PHP 7.4 so you will be fine

Thanks, I downgraded the reported site above.  There other two are not displaying errors on the front page, but the errors are in the database.  I cannot downgrade one as there are other tools that require 8 on the server.
