I have problem with avatar when a member add a avatar to his profile you can see the avatar in the postbit legacy like this

but in the member profile it buggy:

what the problem can be?

Have you tried on a unmodified default style?
Have you tried with all mods disabled?

I tried to disable mods still the same problem
tried the defualt forum style have the same problem

in the profile avatar link is :
http://www.ymarket.org/image.php?u=5...170&type=thumb

and in postbit:
http://www.ymarket.org/avatars/fear?dateline=1423321170


from where the problem can be?

Those both look OK to me.

the problem is if the member upload a avatar
If he use a custom avatar from Internet link it works

Only from upload the problem from where it can be

Seems like it is only with some users, have them reload their avatar. With all mods disabled.

Seems like a bug in vBulletin? When I check the response of the first link I see:

Warning: imagejpeg(): Filename cannot be empty in [path]/includes/class_image.php on line 1430.
When I remove "&type=thumb" from the URL, it works fine.

What version of PHP are you running?

You should really upgrade you vBulletin to 4.2.2, you are running 4.2.0 which has many unpatched security vulnerabilities.

Last php version

The problem isn't from mods I tried to upload avatar after I disable everything and have the same problem

That don't help, what is the version number?
Is the customavatar directory been chmod to 777?

If it is not, then chmod it to 777, then go to ACP --> Maintenance --> Update Counters --> Rebuild Custom Avatar Thumbnails.
