layerslider not viewable

  • John Schrock started the conversation

    With the upgrade from layerslider 7.5.3 to 7.6.1 our map made with layerslider stopped working in some areas. My personal machine and a couple of servers no longer can see the layerslider/map. It is fine on many other machines but I don't know how many can't see it. There is also no error displayed. It is also true for all browsers. 

    The only indication of any problem is witht he old IE11. It says:

    LayerSlider: Multiple jQuery issueIt looks like that another plugin or your theme loads an extra copy of the jQuery library causing problems for LayerSlider to show your sliders. Please navigate from your WordPress admin sidebar to LayerSlider -> Options -> Advanced and enable the "Include scripts in the footer" option.

    I tried what this said, but that doesn't help. Attached is what it looks like for me. Presumably, it may be visible for you. What things can I try or other data would be helpful for troubleshooting. Or, can I downgrade to 7.5.3 without breaking anything (would need the zip). I did this "kindof" by going to an older snapshot of the server but there could have been a WP upgrade as well then so multiple variables may be in place. 

    Please Advise.

    Hello Alan,

    Thank you for getting in touch with us. My name is George and I'm happy to assist you today. I appreciate your patience while we've been working towards your ticket.

    I've checked your site with Chrome, Safari and Firefox. For me, the slider is working fine. This issue can be caused by cache/optimizer plugin. If you are using any of these plugins, please make sure to clear/purge cache files. That should solve your issue.

    The IE11 error message is from a different issue which will be fixed in the next release of LayerSlider.

    Hi George,

    That is the case for my colleagues as well. I had just noticed that the older version was able to be downloaded from my purchase portal and I just changed to 7.5.3 and can confirm that the map works OK for me with that version. So, it is something with 7.6 and my systems. I am not running any optimizer plugins on that site. It would also seem, if that was the case, it should be true for everyone. 

    One thing to note, though I even uninstalled it to test the theory, is that all three of these locations have avast antivirius installed. Also, though, my wife's system has this and hers was fine. It is a strange thing. If it was just my system I would be OK with that, but since I could also replicate it with a few servers, that also is strange. Maybe we wait until the next release comes out and see if that goes OK unless you have some other thoughts.

    Hello Alan,

    Thank you for your fast reply.

    LayerSlider should work well with Antivirus-protected systems. There was an issue at GoDaddy web hosting company some releases ago: they mistakenly detected a file in LayerSlider as malware in some clients' websites, but this issue was solved almost immediately. Could you please open the web inspector of your browser and see if there are any JavaScript errors on your site?

    Hi George,

     

    Sorry for the long delay. Since I had to revert back to a pervious version and this is on our production environment I needed to take some time for snapshots/etc. in order not to mess something up and time has been tight this last week.

     

    I can confirm it was perfectly fine on 7.5.3 but then when I did the plugin update the layerslider the map went away again. It was updated to It is updated right now to the latest of 7.6.7.

     

    I went ahead then and downloaded 7.6.0 and that also is affected. So, it seems there was some major change between 7.5 and 7.6 that is causing this.

     

    There are a number of warnings on the page. The only error I see is this:

     

    Uncaught SyntaxError: expected expression, got '<'

     

    It was there still, though, with 7.5.3 so I don’t think it is the cause.

     

    I have tried to disable all of the plugins I thought could be a conflict (other than wordfence security which doesn’t allow me to do) but that hasn’t helped. There are some others that I don’t think would be the case (forms tools that aren’t on the page).

     

    I know it is really hard to diagnose when you can’t recreate the error. The only thing is there must have been a coding/library change between 7.5 and 7.6  and maybe that would give a clue to what might be a conflict. We are using wordpress Network – so multiple sites on one instance.

     

    Thoughts?

     

    Alan

    Hello John,

    I can see that the latest version is running on your website. Do you still have the same issue with 7.6.7? Because I cannot reproduce this issue, there are no JavaScript errors on your site, and the slider is working fine for me.

    Best Regards,
    George | Kreatura Dev Team

  • John Schrock replied

    Yes, this is the latest. As I said, it is just a few systems, not all that are experiencing this - my own machine and two server machines. Was there a technology change between 7.5 and 7.6?

  •  137
    George replied

    We are constantly adding new features, fixing bugs and trying to optimize the plugin: https://layerslider.com/release-log/

    Honestly I don't know what can cause this issue. On these machines, the operating system is the same? And the slider fails in all browsers, but only on these machines?

    Best Regards,
    George | Kreatura Dev Team

  • John Schrock replied

    Yes, there are 3 different machines and it is the same (2 are Windows Server ) and my Windows 10 machine. All browsers are affected. From the same network, other computers work. With 7.5.3 everything works. Moving to 7.6.x (without any other plugin changes in WP) the layerslider doesn't show up.

    I guess for now we should just close it unless I can figure out some other way to get you data about it. The challenging thing is that I am one of the website managers, though we don't edit the layerslider that often.

    George replied

    Could you, please take a screenshots on one of the affected machines in all browsers with an opened browser console where I could see the possible JavaScript errors? Maybe that could help me to find out what happened.

    Best Regards,
    George | Kreatura Dev Team

  • John Schrock replied

    I probably can't pull off doing all due to time constraints, but could try one. You will see the screenshot at the bottom of the ticket for what it looks like in Firefox. I did notice this in the console relating to layerslider:

    Could you, please temporarily disable the GDPR plugin (and make sure that complianz.min.js is not loading on your site) and try it again? Because the first message about layerslider.utils.js is only a warning and that should not cause an issue like this.

    Best Regards,

  • John Schrock replied

    I had already done that along with most other plugins to no avail...

    I did double check, though, and it didn't matter.

    George replied

    Could you, please create a temporary wp-admin access for me? If you don't mind, I would like to check the plugins and settings in the wp-admin interface to see if I can find what could be causing this error.

    Hello John,

    I was able to log in and I've opened Firefox with your website. The slider is now working for me. Did you change anything? How can I reproduce the issue?

    That is so very strange! I logged in as well with the same username/password and still don't see it. There must be something blocking it in my personal machine and somehow that is also passing on to the RDP connection - though that is also very strange. 

    I am more convinced this is unique to me. Feel free to close this ticket and not worry about it. If I figure it out, I'll go back in and update it (or if you want to keep it open that is also fine. I'm traveling starting today for the next 2 weeks so probably won't look at it much, if all, during those days. 

    Thanks for looking as you can at this!

    Hmmm... are you using a laptop/display with touch screen?

  • John Schrock replied

    yes, my laptop has a touch screen.

    George replied

    Now I understand what caused the issue. In the previous release of LayerSlider there was a bug: the slider thought that it was running on a mobile device if the device had a touch screen (even on a normal laptop). And I bet that your slider has the "Hide on mobile devices" feature enabled. ;-)

    George | Kreatura Dev Team

  • John Schrock replied

    Yes, that is the case because in that case we display a different menu. But, the content management software we are using is looking for device size and since it wasn't the right size it didn't display that other menu (which would have also been confusing, though. It is interesting that the RDP sessions carried that information over to them.
