Hi Mark!
Thanks for reaching out to us! Let me help you with that issue.
I’m not sure I understand exactly the issue you are having. Could you please explain which tabs are not working for you? Is that in the backend of your site? If it is, please share a screenshot of the issue you are having.
Also, please see if there are any console errors by inspecting the page? We have an article that explains how to do that here > https://theeventscalendar.com/knowledgebase/using-google-chrome-developer-tools/
Additionally, this can be related to a theme or plugin conflict, so to narrow the problem down please go through the steps provided in the testing for conflicts guide > https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ and let us know what you find in the process.
Regarding the discounts, you should check out the following page and even subscribe to our newsletter so you can be the first to hear about any new promotions > https://theeventscalendar.com/deals-coupons-discounts/
Thanks,
Victor
