Hi Sanjeev. You posted in our Translations forum regarding Event Tickets Plus (ET+) from a user account that doesn’t have any purchases associated with it.
We only answer support questions in each product’s respective forum (which you can only post to if you have a license).
We have not been seeing any fatal error like this in the current version of ET+ (I’m not sure about past versions). I also do not know what version of Event Tickets (ET) and ET+ you have.
If you made your purchase(s) through a different user account, please login to that account and then post in one of the paid forums.
Thank you for your understanding and thank you for using our plugins.
