Any idea what’s going on? It started happening after the latest update I just ran.

Hi Daniel,

Thanks for reaching out!  I’m sorry to hear that you are experiencing this issue!

Are you seeing any issues with functionality on this site when the error is there?

As a first step, let’s try to rule out if there is some type of conflict at play.
This is usually because of:

1.    A conflict with another plugin

2.    A conflict with your WordPress theme

3.    A template customization for the Events Calendar that requires updating

When it comes to that type of issue, it is preferable to troubleshoot in a staging environment if you have one.

A first quick test is to simply temporarily revert back to a default WordPress theme such as twenty-sixteen to see if the issue persists.

The next step would be to go through our testing for conflicts procedure and let us know what you find out.

Basically the goal here is to revert back to a bare WordPress installation to see if the problem persists. It also allows us to pinpoint what the cause of the issue is.

But, before you do that, there are 2 things I would advise:

1.    Make a backup of your database

2.    Consider activating a “Maintenance Page” plugin if you are doing this on your live site (to minimize impact on your visitors)

Let me know how that goes!

 

Thanks,

Hi Jaime,

I did all the troubleshooting and the issue still persists. Now with the latest version there also another issue mentioned on the following link: https://wordpress.org/support/topic/last-update-causes-issues/#post-9670962

Your plugin is causing conflicts with Advanced Custom Fields.

Please advise. For now I have rolled back to 4.6.3 and I still have the issue mentioned on this thread.

Thank you!

May this is related to the following map issue: https://wordpress.org/support/topic/google-maps-bug-in-listview-related-to-4-6-3-release/ ?

Hi Daniel,

Thanks for providing me with all of this information.  I’m sorry that you are seeing additional issues with your site since updating, however I’m glad to see that you have a workaround for now.

Let’s start off by working on your initial issue.  Would you mind sharing a screenshot of your map settings with me?  Also, if you could tell me what triggers that error to appear, I could try to replicate things on my end.

In the meantime, you may also want to ensure that you have everything set up properly with Google Maps:

Please let me know if there is anything else I need to know in order to replicate this issue!

 

Thanks,

Hi Daniel,

I just wanted to follow up with you and let you know that I got some more information on your issue.  It seems that there is a bug related to our geolocation code.  A workaround for this issue at this time would be for you to roll back to Events Calendar version 4.4.18.

We apologize for the inconvenience caused by this glitch and we are actively working on a solution for this.  I cannot guarantee when it will be fixed, as it’s in the development team’s hands now.  They need to assign it, code it, test it, and schedule it for release.  The good news is that you will be contacted as soon as a fix is available.

As for your other issues, if you are still experiencing them, I’d recommend opening a new thread for that issue, so that we can deal with each issue separately.

Please let me know if you have any questions in the meantime.  Thank you for your patience as we see this through.

 

Thanks,

Jaime

Hi Jaime,

Just to follow up, I’m running the latest version of The Events Calendar (4.6.5) and Events Calendar PRO (4.4.19) and I’m still having the issue.

Thank you!

[Daniel Maier]

I rolled back Events Calendar PRO to 4.4.18 and now I’m getting the following:

Hi Daniel,

I apologize for the delayed response.  As you’ve discovered, rolling back to 4.4.18 isn’t a workable solution anymore, and we are actively working on creating a fix for this issue.  I apologize for any inconvenience this may cause you and we appreciate your patience throughout this process.

Please let me know if you have any other questions in the meantime!

 

Thanks,

Hello,

Any update on this? My server logs are getting filled with this. 🙂

Thank you!

[Jaime Marchwinski]

Hi Daniel,

I wish I had some more concrete news for you, but unfortunately this bug is still being worked on and I don’t have a definitely timeline of when it will be resolved.  It has been bumped up to a high priority bug and you will be notified as soon as a fix is available.

Thank you for your patience!

 

Thanks,

Jaime

[Daniel Maier]

Ok Jaime,

This is filling up my error log making it hard to catch other bugs. 🙂

Also I don’t think the option “Notify me of follow-up replies via email” on this ticket is working. I never got your replies via email.

Thank you.

[Jaime Marchwinski]

Hi Daniel,

I’m sorry that you are not getting notifications via email.  Just as an update, this bug has been upgraded to high priority and we are actively working on a solution for our users.

You will be notified as soon as a fix is available.  Please let me know if you have any other questions in the meantime!

 

Thanks,

Jaime

[Daniel Maier]

Ok, I believe this is causing my server to timeout not only this requests but others. Please fix this ASAP.

Thank you!

[Jaime Marchwinski]

Hi Daniel,

We are actively working on a fix for this bug and progress has been made since my last response to you.

This will be released soon, and we really appreciate your patience and understanding throughout this process.

 

Thanks,

Jaime
