Modal not showing after browser update

I have been using PeppeL-G modal package with bootstrap 4 and it has worked fine until my chrome browser updated. Click events to show modals don’t result in any errors neither does the modal show up.

Modal shows in older versions of firefox and Opera browsers.
I believe the issue may be related to this but not sure what to do make this package show the modals.

I need help fixing this issue, its critical!

Is there a public link we can take a look at?

The package itself is relatively simple, so I can’t see how a browser update would affect it. Nor does it use window.showModalDialog, so that shouldn’t be related (unless you are using it instead of

I would start by adding a breakpoint at the point where you call and stepping through it from there to work out where it’s going wrong

Thank you so much for replying;
There’s no public link unfortunately, site pulled down because of this challenge. I am trying to get it back so you can have a look.

the only explanation and change that has happened that i can think of. It still work in some browsers so that makes it really hard for me to figure out what else could be the problem

in the meantime,

// this code is what initiates the modal show{ 
      'click .confirm-button'(e,t) {
        if (!Meteor.userId()) {
          // show guest Signup Modal

// modal code

I am trying to push it back

not very good with debugger yet, any resource to how to do that well?

There aren’t any time slots for the .confirm-button to appear. So I can’t test what happens when I click the button that triggers the modal.

But if I directly call'guestSignupModal'); in the browser console, it works just fine on latest Chrome Dev 77.0.3854.3 and on latest Chrome Stable 75.0.3770.142

Have a look at the Chrome Devtools page

It will be a bit more difficult because all the code is minified in production, making it harder to read.
Does this same issue happen when run in development?

I just tried with the debugger and surprisingly the modal showed up! there is no error on the console either.

I am using chrome debugger with visual studio code
It still doesn’t work in the normal chrome window

I guess its the timezone effect. yet to figure that out. But you can select another day by clicking the available days to get you slots for that day

now i am confused, using the debugger it shows up with no errors but main chrome browser will not show it.

Yes it does! still wont show in chrome but shows in opera and firefox.
and just now, it shows in chrome debugger page but not in regular chrome page

No matter what day I select I am given no options



I have used incognito mode, i have changed my time zones and all works. I am able to get time slots. Please can you try with incognito mode or vpn to change your timezone? I really need help fixing the issue.

Just discovered that changing timezone to something like this breaks the time slots code. But that’s for another day. image
so im sure you are in a similar timezone.

Please change to london timezone and you should be able to get time slots so you can help me figure this out

Changing local timezone to US EST worked.

Modal still shows in Chrome 75 and 77 from cold start without devtools open

this is my chrome version

Google Chrome is up to date

Version 75.0.3770.142 (Official Build) (64-bit)

at this point I am just going crazy!

Just to be sure I tried it in a Windows 10 VM with Chrome 75.0.3770.142 and it worked there as well haha

I will just continue working on it then.
Thank you so much for your time. I really appreciate it.

Will you be interested in helping me figure out how to make this work in all timezones? :slight_smile:

I use moment and all but i guess my logic is still faulty

@coagmano so we spent the entire day and nite combining through my code only to discover that the browsers had stored some cookies information and some data which after clearing and resetting makes the modal work just fine!

At least I have gone through debugging and also found a way to mimic other timezones all of which will help in my journey!

For anyone who may run into strange behaviors like this, well check your browser settings, cookies and data stored.
Thank you once again @coagmano
