End Portal not working

The End Portal seems not to work in the newest version, any fixes yet?

Well no, the ended portal is trick to figure out like there is many different ways

Did you have a server with Multiverse installed ? Did you check on the server configuration if the end is active ?

Just reinstall Minecraft. And if it's still continue, well I don't know what to do.

Has probado a cambiar el mundo, se que es dfrastico pero te aseguro que funcionara

The older versions of the game had a greater quantity (and in my opinion better) mods than what we have today; personally I used to like 1.7 + 1.8.9 because of the combat aspect; I haven't really touched any of the versions after that.Just reinstall Minecraft. And if it's still continue, well I don't know what to do.
