I think the issue is in here (function investInternal):

 if(!earlyParticipantWhitelist[receiver].status) {

Receiver (the caller of the buy method), is not on the earlyParticipantWhitelist.

Thus, the transaction reverts

  • sir, what an i do now? this is already created nah? can i change this? how? please Jul 21, 2018 at 9:55
  • It seems that only the owner can put you on the whitelist. Maybe you should contact support of the crowdsale

  • sir the problem is im the one who created this using poa wizard. actually tried a lot, according to your knowledge, if i remove the whitelist it will be able to invest for everyone? now, i can invest only the addresses i put as whitelist addresses. that's the problem sir. i dont know what to do :( Jul 21, 2018 at 10:07
  • What you should do: accept my answer, create a new question with detailed information on what you want to do and what you know about it not working. Add the links you provided in this question as well.
