Hi there,
I am still using Events Calendar Pro 2.0.11 on my website – I did try to upgrade to 3.0 when it came out but it just didn’t get on with my site. And 2.0.11 still works fine 🙂
I’m now about to upgrade to WordPress 3.8 and I’m wondering how my older version of ECP will cope with that. Tough question to answer I know.
Anyway, I’ll ask: Do you know of anyone who is using the Events Calendar Pro 2.0.11 and has successfully upgraded to WordPress 3.8 ?
Well, I tested it locally and it seemed to work fine. No problems that I could identify running WordPress 3.8 and Events Calendar PRO together. So give it a go, but I’ll ALWAYS recommend backup, backup, backup. 🙂
