I meant to add that existing filters do work (can be executed), but I cannot amend them

Hi,

Your PHP version is much too old.
The function war introduced on PHP V7.3
So your PHP is older.

Note that, as defined on prerequisites ( https://www.projeqtor.org/fr/product-fr/technical-fr/51-setup-fr/33-product-prerequisites-fr), ProjeQtOr V12.2 is compatible with PHP7.4 => 8.3
 

Hi,

This is a bit confusing, because my client's Projeqtor instance is being hosted by you - not locally. At least I assume it it. The web address is **.progeqtor.org/view/main.php# (I can provide the client ID, but didn't want to put it in a public forum)

I'm not sure how hosting works (i.e. why my client is using Projeqtor V12.2.3 and not the latest version).

Sorry, if I've said something that makes no sense.

Regards,

Ian

Please send us information about your instance name.

aw is the instance name

Thanks.
Your instance is already planned to migrate to a new server
On the server hosting your instance, another instance is hosted and is on a very old version of Projeqtor (client refuses to migrate) that forbids to upgrade php version.

Thanks for the update 🙂
