Welcome back, Gustavo 🙂
When you visit Events > Settings > Licenses on your WordPress site, do you see a “Valid Key! Expires on 2018-01-08” message beneath the Event Aggregator license field?
A recommended article in this instance is our Finding and inputting your license key Knowledgebase article. You’ll also need to review our Testing for conflicts guide to ensure a theme and/or plugin conflict is the cause. This is a required step to continue receiving support.
Lastly, please include your System Information as a private reply. Thanks and have a great evening!
