you didn't need to post the server log nor that fake line, first of all let me explain what happened here, line 430 is not meant to be the line in your script if you read the warning it says:

Код:

\YSI_Data\..\YSI_Internal\..\YSI_Core\y_utils.inc(430)

see that, it gave you the location of the file, it's the y_utils include it already has isnull defined which is also either defined in your script or in another include that's what redefinition of constant/macro means, what you can do is either search through your includes and remove the redefinition of constant/macro or rename the one in y_utils but idk if that will cause problems i suggest renaming/removing the other one.
