problem after update plugin Event calendar

I had a more serious problem when I updated from 4.0.5 to 4.0.6 (Events Calendar and Events Calendar Pro). The update somehow messed with my permalink structure and broke nearly all of my event links. I restored my site to 48 hours ago and fixed the problem. But I don’t recommend updating to 4.0.6 if you’ve ever changed your website’s menus or links in any way. The Update should not have messed with the permalink structure, but it did and gave me 404 errors for nearly all the events on my site. I was able to fix it by restoring my site to the 4.0.5 versions, but I’m terrified by 4.0.6.

Hi,

Sorry for the issues you are having.

We are not sure what changed, but it appears this issue is coming from a conflict with Beautiful Math Module of JetPack.

If you disable that module does it fix the issues?

On my testing site if turn on the module I see the issue you are having and if I turn it off it goes away.

Let me know if that helps.

Thanks

So that might not fix the issue, but we think we know what is causing this.

It was due to a change to make it more compatible with other plugins and themes, instead it backfired.

So to resolve this for now please copy the contents of this:

https://raw.githubusercontent.com/moderntribe/the-events-calendar/89d4fa6487e39b233a774c4005f1be57da635e61/src/Tribe/Templates.php

to this file here on your site:

plugins/the-events-calendar/src/Tribe/Templates.php

That should then resolve it.

Let me know if that works for you.

Thanks
