I was able to create a new crowdsale witha few changed parameters and get it working. The changes I made were to - no whitelisting, ticker symbol - was a 3 letter than a 5 letter and allow changing parmeters of the crowdsale. It worked this time without error. There was clearly some glitch the last time as I do not see the ILTLT token I created on the Kovan network but I do see the GNT token created in my second attempt. I am leaving issue open for a review

@pratimasethi do you have the same problem with your created crowdsale on the main instance of Wizard (https://wizard.poa.network) ?

@pratimasethi I think is something related to the truffle instalation Could you see if this fixes the problem for you?

npm uninstall -g truffle
npm uninstall -g solc
npm install -g truffle
