Today ICS Calendar version 10.7.1 and ICS Calendar Pro version 4.4.3 are available. I strongly encourage users to upgrade both. (If you are running Pro, be sure to also get the 10.7.1 upgrade to the free version.)
The recently introduced Load JS and CSS files on wp_enqueue_scripts action option has been removed, replaced with more solid logic that both ensures that the scripts do not load unnecessarily (i.e. on pages without a calendar), and that they load at the correct time in the page.
Since this feature was introduced a couple of weeks ago, I’ve been attending to a handful of seemingly unrelated support issues that, it turns out, are all due to this setting. Actually, not this setting itself, but the changes that were introduced that required this setting to be created in the first place. The new approach is the “right” way to do this, but as is so often the case in the sprawling universe of WordPress, I was not aware of that when I introduced the “wrong” way earlier this month.
If you’ve been experiencing issues with your calendars not loading correctly — or at all — for the past couple of weeks, this change is likely to resolve the issue.
A note for ICS Calendar Pro users whose setups include a load balancer, proxy server, or other “unusual” network configuration: There has been a small change in how the license key validation API determines your server’s IP address. It is possible this change will require you to re-enter your license key. But, this change was specifically introduced to help in situations where you are already having to re-enter your license key repeatedly. Because of the nature of the problem, I don’t have a way to test this directly, so your feedback is welcomed.
