Context initialization failed

[alf_developer09]

Not able to login Alfresco,getting this error on Development server only whereas on local server amps seems to work fine.
PS: Before deployment of new amps,I deleted all workflows "delete all workflows imeanit" through admin console.Dont know if this lead to the below error.

Hi, your log is not full. The reason of error follows after "caused by"

You should check and validate your installed extensions, fix them and restart tomcat

When extensions will be correct, you will be able to login  

Good luck!
