Sorry Mot3rror,
But what exactly i should do now??

I changed the code once and it didn't solve the problem.
I changed this comma to a new one.
And tried to separate tags with the new comma but they were not separated.

What exactly should i do ?!
Sorry if you said something i didn't understand.

fetch_tagbits is the output function, you need to find out what is going on at the input side of things. Unfortunately I don't have access to vB 3.7 at the moment so can't give direct instructions, however it would be useful for check to see if there are any tag "storing" functions or otherwise look at newthread.php and see what is happening when the tags are being written into the database.

Thank you Opserty for your caring
But acually I'm not a programmer or a coder.
So It's not easy for me to do such things.

You know, this really is a big project. I just did a search through the 3.7 files for "taglist" and found several functions that deal with the list and they all "explode" or "implode" on the comma - fetch_valid_tags and insert_tags_thread (I think this one inserts the comma) and rebuild_thread_taglist. Those three are all in functions_newpost.php and you would have to make all the same sort of changes to all those functions. I also found the file threadtag.php. I'm not sure what's in there, but I would guess there are changes to be done in there also.

Are you sure no one has tackled this before?

It is big..
and yes i think no one bothered him self with this before!
But what I'm wondering more Lynne is why the vBulletin team - who created the code - doesn't want to help us in this, If they don't, who should do then !!

I guess my suggestion would be to post over at vb.com about getting together a few users with this problem and seeing if you can collaborate to fix it. I think vb isn't willing to tackle it because they don't have the time for a fix in 3.7. 3.7 was supposed to just be a quick intermediate release before 4.0.

4.0 !!
and what about :
3.7.0 ,1,2,3,4.....
3.8.0 ,1,2,3,4.....
3.9.0 ,1,2,3,4.....

I really don't know ..
I will contact the support system again.
If they don't give us the solutions who should do !!!!!!

There isn't going to be a 3.8 or 3.9. And, if there are revisions for 3.7, they are supposed to only be for bug fixes. They are not working on it to add anything any longer. It's full speed ahead for 4.0

That's great!!
