Deprciated function error messages

I run scase grid applications on three websites two are working fine one is reporting a php error on all the apps.
I checked the versions of php on all three sites (they are on separate accounts) and all are 7.3.28

The faulty one returns error:

Deprecated : Function get_magic_quotes_gpc() is deprecated in /home/customer/www/applications.aa-wso.org.uk/public_html/dir/script-case/tabs/1/1.php on line 4454
Tried reinstalling one of the grids - still the same.

I think it points to the web server or the theme as the other two sites are ok.
Just a hunch if someone else has seen this error?

This function is deprecated since PHP 5.4 but the warning should only be present on PHP 7.4 and up
Are you sure that your website reporting the error is on PHP 7.3.

You can remove the warning with this

error_reporting(E_ALL ^ (E_NOTICE | E_WARNING | E_DEPRECATED));

Thank you I will add this line.

The web hosting is saying that I am running PHP 7.3 from their version control app

Not sure if this also applies to my website (wordpress) ?
I am using the latest version of wordpress.

Thanks jlboutin60 - that got rid of the error message!

Will I need to add to other scriptcase apps the I create for the site, or is there a global way of switching the error messages off?
Regards Steve

If you have access to the php.ini file you can do it globally there

But it should not appear in 7.3, be sure you are not in 7.4 because it’s not supported by Scriptcase and you can have a lot of strange behavior on the wrong version

Thanks
I will do that
I double checked and the host server has a php version selector and set for 7.4
I changed the version to 7.3 but the error messages were still showing.
I added your line of code in the appropriate place and all is well.
Perhaps going back to version 7.3 did not actually switch things back to 7.3?
