On my server I use Multiverse Portals for the majority of the teleporting. I just recently got a generator that makes a floating islands world (http://dev.bukkit.org/server-mods/floating-isles/). When i tried to set a portal to tp to the new world, it wouldnt work. I tried different names, different locations, and different destinations, but the portal will not work. I then had users complaining about another portal not working, one that teleports to a 8x scaled world (http://dev.bukkit.org/server-mods/maxiworld/).
I would greatly appreciate it if someoe were to help or suggest how to fix this issue. I am currently using essentials warps to teleport players to these worlds, but i would like there to be portals since they look better, and dont cause a delay for default players (I have 1 second delay before tp).
Thank you!

Those new worlds are imported into Multiverse (show up in /mv list), right? Also, what do you mean by "doesn't work"? Nothing happens? An error message? Something unexpected?y

Nothing happens at all. Everything says it was set up properly, but then when I walk through it does nothing. I'll try /mv list though that might be the issue

It shows up on the /mv list, so that probably isn't the error. I also realize that I have created quite a few portals (about 80). Could that possibly be an issue?

I have exactly the same issue - and have the feeling that it have to do with the location were certain portals are set. for example, my spawn is close to the middle of the world, I created a lot of portals there, and every portals close to this locations are working in both directions - everything is properly set with the create, select and modify dest mvp commands - everything looks good in portals.yml
one example from portals.yml

BUT, some portals back to the spawn area are not working, i also tried it with differnt names - other locations and so on.

It have nothing to do with any permissions (this was in the past another of my problems: solved)
if i use /mvtp to teleport directly as an admin to the portals, both portals can be reached.

What I found out:
if I created a portal in a "far from spawn" region, - the portal from spawn to Fare away works, but not fare away back to the spawn region - and now i create a total new portal pair for a 10 block short distance teleportation close the the "fare away" portal .... both directions of this short distance portals are not working.

I am using only residence for area protections, but i also removed the protected zone arround the fare away location.

My world is from -4000 to 4000 in x and z ... and i have the feeling that it have to do with locations containing higher xyz numbers. (but i am not sure)

the next same behavior to the original issue poster here is that I am also having a lot of portals, and 80+ will not be the end. At my world, I am having an adventure, self area protection world with no player self teleportation possibilities (exept for i time each hour back to the spawn) world map, so planed portals are essentiel.

I solved my problem - i read again the documentation for multiverse portal and found the command /mvp modify dest here ..... and during trying to create additional portals, I found out that the "here" command recognized a portal which was not set by me then expected ... the portal covers a really big area and overlaped my other portals where i tried to set .... after removing the misplaced "huge" portal area, the other portals worked like expected. maybe the create command should try to calculate if a portal "area" is too big and give a hint or warning during creation of a portal zone.

I have kind of the same problem, just more confusing. I only have THREE portals in total and I'm trying to set portal #1 to portal #3, but when I walk through, it doesn't do ANYTHING! Could I get some help with this?

Here's my error when trying to go through, apparently: http://pastie.org/8221345

I have the same problem! help would be much appreciated! portal_b TO portal_a works but not portal_a TO portal_b. Done everything that has been said on this post but still not working unfortunately.

P.S: I know this is an old thread but I really need the help!

P.P.S: Mutli-verse-signs work just fine both ways! But I want the portals.
