`CakeResponse` referencing undefined variables in `compact()` call triggers errors/notices

Question

I’m updating my first CakePHP application on a web server, but pages show errors which are at the end of this post. I can’t find the file(s) which have not uploded correctly. Thanks for help.

CakePHP version : 2.9

Error messages :

Notice (8): compact(): Undefined variable: etagMatches [CORE/Cake/Network/CakeResponse.php, line 1171]*

Notice (8): compact() [function.compact]: Undefined variable: timeMatches [CORE/Cake/Network/CakeResponse.php, line 1171]*

Notice (8): compact() [function.compact]: Undefined variable: subject [CORE/Cake/Utility/ObjectCollection.php, line 128]*

I think you are going to have to look at all the error mesages in your logs — RiggsFolly, Jul 12 '20 at 16:53
When upgrading, it is not sufficient to just copy the new files. Read the migration guide for step by step instructions. — Markus Zeller, Jul 12 '20 at 17:07

As of PHP 7.3 compact() will trigger an error when referencing undefined variables.

This has been fixed in CakePHP 2.10.13, either upgrade your application (preferred), or downgrade your PHP version.

I have just downgraded the PHP version of the server and I no longer have this error. Thank you – Uultron_10 Jul 12 '20 at 19:22
