With out a console log error I'm not exactly sure what is causing this. You said this only happens on the server? If NEI works fine in the modpack when you try to play SSP. Then my suggestion is to open your server folder inside the save folder and delete your NEI.dat and/or NEI folder located there. This is where the NEI search, configuration and other information about NEI is located. It is safe to delete, you will just have to redo your NEI options.

im playing on public srv and it doing only for me that error

It almost has to be something on your machine then. Please try my suggestion about deleting the file/folder. The only other thing I can think of is reinstalling the mod pack with a force update. Or if you did not follow the recommended install guide try following it closely.

Edit: Just did a search for the first line in the error and the first link that appeared suggested the same thing I initally suggested of deleting the NEI.dat file/NEI folder and it worked for that user.
