I know this is a known issue but it just started a couple of days ago for me. I can no longer imbed my calendat on my homepage which is what my website is built around. My license key is getting the following error:
There is a new version of Event Aggregator available but your license key is invalid. You may need to download and manually install the new version. You can check the status of your licenses and download plugins by logging in to your account on theeventscalendar.com. View what’s new with version 1.0.
I have deleted and redownloaded the most current The Events Calendar Pro and it has not resolved the issue.
