can a Vbulletin upgrade affect ranks?

I made an upgrade last sunday
and it now my google traffic dropped a bit again.

Can it be that an upgrade does affect your google ranks for a short time?

thanks in advance for your opinions

Please move the post if possible

Did you edit your template at all? How long was your board offline?

there were 2 little template edits to do
1 in memberinfo and one in postbit legacy
the forum was offline for not more than a few minutes

I do not think the drop was caused from the upgrade with those circumstances then. Have you changed anything else? Also has your traffic been improving since the drop?

Also has your traffic been improving since the drop?

no traffic has not improved , not yet


I have changed again a few days ago to add internal rel no follows
which i had disabled before.

Really dont know what is better to do with the rel nofollows
also for the outgoing links

Since we have so many affiliate links for casinos
People who i talked to all advised me to sure add a rel nofollow to all outgoing links, this i did about 3 month ago.

Was this ok to do?

I find we get less and less searches through google

or easier understanding
about 3 month ago i changed the default rel no follow setting

added a rel no follow to all outgoing links

and disabled this

Add rel="nofollow" to ALL Sorting Links

Now a few days ago i did enable the above again
