I’m sorry to hear this, Bruce!
1. I cannot recreate this behavior—can you share links to specific event pages on your site where the maps fail to show up? I will check those out and see if I can spot any errors in the JavaScript console, etc.
2. Next, can you try doing the complete set of troubleshooting steps on this page → https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ After EACH STEP in that process, check back on those pages where the maps fail to show up — do they start to show up anywhere along the way in the process of this testing?
Let us know what you find!
Thanks,
George
