WPRocket JavaScript Deferred Issue

    When using EventKoi with WPRocket, activating the “Load JavaScript Deferred” WPRocket option breaks the API call that fetches the body of the calendar. Adding the EventKoi JS file paths to the WPRocket exception list does not resolve the issue.

    To recreate the issue have both plugins installed. Under WPRocket > File Optimization turn on “Load JavaScript Deferred”. Log out and visit a page where you have the calendar shortcode installed or the …/calendar/your-calendar-slug/ page that the plugin creates.

    The calendar will only display gray placeholder blocks and the browser console shows a JS error of Failed to load resource: the server responded with a status of 404 and an error saying Failed to load initial calendar

    Hi, Thank you for the detailed support request and for letting us know exactly how to recreate the issue.

    I have gotten in touch with WPRocket for a copy of their plugin so that we can troubleshoot this issue. Depending on their reply, we might also attempt to solve the issue by using WPRocket’s documentation on Load JavaScript Deferred, but would then need your help to test and see if the issue is resolved.

    Hi, I was finally able to get a license from the WPRocket team and attempted to replicate the bug you mentioned but was unable to do so.

    Here are the steps I took:

    1. Installed EventKoi Lite (v1.0.13) and WPRocket (v3.20.0.3) in a brand new instawp site
    2. Navigated to WPRocket Settings
    3. Checked the Load JavaScript Deferred option and saved changes
    4. Opened up a calendar using the calendar page created, as well as created a new post and added a calendar shortcode.
    5. Both default calendar page and new post with shortcode were able to load the calendar with no issues.

    Here’s a short video demonstrating this: https://share.cleanshot.com/1dmzQ472

    Are you able to try again on your end to see if the problem is still occurring? I’ll mark this as closed for now, but if you still encountering this issue, please reply and share additional information if possible.

    Thank you!

    The problem is still occurring on my end. Based on that recording it looks like you were still logged in when you went to view the calendar. This issue only occurs for non-logged-in users. Hope that helps!

    Hi! Thanks for reaching back out.

    I just tried it after logging out and was still able to load the calendar.

    I suspect the issue is caused elsewhere. Have you tried replicating the issue with WPRocket deactivated?

    On our end, I have noticed a similar issue happening on our own site: https://eventkoi.com/calendar-examples/. Site visitors occasionally tell us that the calendar isn’t loading. This is the error we get on our end: https://share.cleanshot.com/g3xsf7Cl Is it similar to what you see?

    Clearing the cache has worked for us in the short term as we look for a long term fix.

    I am beginning to suspect the issues are correlated (or even the same issue).

    Now that I know it’s causing issues for you too, I’ll make it a priority for us to get this solved.

    If you are able to share any additional information on your end, that would be very helpful. We will look into it regardless and fix it as soon as we can.

    Thank you for flagging this.

    I have been unable to recreate the issue with WPRocket deactivated.
    My errors are similar, but not quite the same:
    Get index.js?ver=1762543287:42
    https://sitename.local/calendar/events/eventkoi/v1/calendar_events?id=29&display=calendar&initial=true&_locale=user
    404 (Not Found)
    and
    index.js?ver=1761859018:1 Failed to load initial calendar {code: 'invalid_json', message: 'The response is not a valid JSON response.'}

    I am happy to share any additional info to help get this resolved. Is there something specific I can track down to aid in this process?

    Hi! Sorry for the slow reply.

    Are you able to use this instaWP site to replicate the issue? I’ve installed WP Rocket and EventKoi Lite in there already.

    I’m trying to ensure this is an issue that is isolated to WP Rocket and EventKoi Lite.

    Here’s the link: https://app.instawp.io/wordpress-auto-login?site=$2y$10$0CJk9ytYjB9JUZm/U9K0aeqN1RIzpHbMHERfsnIkdT/KBffkoprl6

    Thank you!

    To follow up on the previous thread…

    The InstaWP site is a sandboxed site that allows us both to work on the same WordPress install via the magic login link.

    Please do not add any personal, sensitive or confidential information to the site as the WordPress admin is public and anyone is able to access it.

    I’ll take down the site once we have finished working on it.

    It looks like either the 1.1 or 1.2 update has resolved this issue. I am no longer getting the error on my site after updating and I am unable to recreate it on the instaWP site with v1.2 installed.

    Thank you for your assistance on this issue!
