[21:57:30] [Server thread/INFO]: [WorldEdit] Loading WorldEdit v5.6.3

I also have these:
[21:57:34] [Server thread/ERROR]: java.lang.NoSuchMethodError: com.google.common.cache.CacheBuilder.maximumSize(J)Lcom/google/common/cache/CacheBuilder;

[21:57:34] [Server thread/ERROR]: Error occurred while enabling Essentials vTeamCity (Is it up to date?)

[21:57:34] [Server thread/ERROR]: Essentials not installed or failed to load. Essenials Protect is in emergency mode now.

[21:57:33] [Server thread/ERROR]: [PermissionsEx] ==== PermissionsEx could not be enabled due to an earlier error. Look at the previous server log for more info ====

I was thinking of reinstalling essentials (cause at the looks of this i think i should)
But PEX I think can be fixed.
This is my PEX pastebin: http://pastebin.com/jn4cR1dr

Someone pls halp :3

 

@SaintFlareGhost It's a problem with your YAML format. Put it through a parser and fix all of the errors it gives you.

 

I HAVE MANY OF TIMES! ITS NOT WORKING.
TRY IT URSELF

Oops sorry for caps^

<merged posts. try using edit. ~Eya>

 

@SaintFlareGhost Why would I do it? You're the one having the problem, and we're here to help you, not do it all for you.

 

@nverdier I've narrowed the errors down to one.
Its still the problem with PEX.
I've used the YAML Parser every time you've told me to and it says that everything is fine.
Here's proof: http://gyazo.com/e01d27fa9e63bdf2f9a981ff122b045e
EDIT:
I tried re-installing permissionsEX and I still get the same error

@SaintFlareGhost Hmm not completely sure... Did you delete the config files? Maybe back them up somewhere and let the files regenerate to see if it fixes the problem.

 

@SaintFlareGhost When you're reinstalling PEX, but you're getting the same error, you cannot use Tabs in your YAML Files. Tabs meaning do not use the TAB key located directly above your Caps Lock key and below the Tilda key on a standard keyboard. If you're using a tab then putting the permission - permissions.* on line 99 once again, then you are causing the plugin to break silly

Do a COMPLETELY clean reinstall of PEX and do NOT edit any file then see if you get the same error. Delete the plugin's folder and restart your server so it regenerates.

 

@Larry Newman It's a problem with size for the CacheBuilder, not tabs... That was fixed a while ago. But I agree with the complete reinstall.
