Upgrade to at least 4.2.3, better still, 4.2.4.

You are running a newer version of php (5.5 +) which isnt compatible with older vB versions.

thank you i have fixed by follow this thread ,

I would consider that "fix" to be a band-aid until you can upgrade your vB to a version compatible with your PHP as Paul suggested. :)

You have not fixed anything, you are simply hiding the errors, some things will break on 5.5, you cannot hide them.

this is i have installed
Latest version available: 4.2.3 Patch Level 2


where there appears ,

--------------- Added [DATE]1480622818[/DATE] at [TIME]1480622818[/TIME] ---------------

There are instructions in the manual on how to do an upgrade - https://www.vbulletin.com/docs/html/upgrade .

Make sure you do a database backup prior to upgrading.
