Hi Martina,
I’m sorry to hear you’ve experienced some difficulties.
After the latest update, I had some problems with Venues and Organisers not working, because the system believed that I had used the license key somewhere else.
Please be assured that the presence or absence of license keys does not actually impact core functionality in this way: whether your key is valid, has expired or even if it hasn’t been entered, our plugins should continue working as expected.
Of course, other bugs can and do surface and I suspect it was indeed some other problem you hit up against with regards to venues and organizers.
Now, a few days later, wordpress keeps telling me that I have to renew my license key.
That’s really strange.
Can you clarify where exactly you are seeing this and would you be able to share a screenshot? Though you cannot upload files directly to the forums, if you can upload it to your own WordPress site or else to a service like Dropbox you could then share the URL in your next reply.
Thanks!
