I am using the same images assigned to both. Funny thing is it is working on my test environment and as soon as i moved it to live server it is now giving me this error on mobile devices only. While viewing it on desktop i get no errors. * Thread Starter [spatwa110](https://wordpress.org/support/users/spatwa110/) * (@spatwa110) * [7 years ago](https://wordpress.org/support/topic/error-while-viewing-on-mobile-devices/#post-11604923) * I tested everything on my side and that is deactivating all the plugins to see if there are any conflicts. I also tried downgrading the wordpress version to see if that was causing an issue but no luck. My guess is it is something to do with your plugin. Thank you. * Plugin Author [thehowarde](https://wordpress.org/support/users/thehowarde/) * (@thehowarde) * [7 years ago](https://wordpress.org/support/topic/error-while-viewing-on-mobile-devices/#post-11604943) * The only reason it would get a divide by zero error here is because it can’t find the mobile image. Try re-uploading the mobile image separately and specify it in the shortcode settings. Or leave out the mobile image if you’re not using it. - This reply was modified 7 years ago by [thehowarde](https://wordpress.org/support/users/thehowarde/). * Thread Starter [spatwa110](https://wordpress.org/support/users/spatwa110/) * (@spatwa110) * [7 years ago](https://wordpress.org/support/topic/error-while-viewing-on-mobile-devices/#post-11605044) * i tried uploading the image and assigned it to the shortcode but no luck. I am still getting the error. * Plugin Author [thehowarde](https://wordpress.org/support/users/thehowarde/) * (@thehowarde) * [7 years ago](https://wordpress.org/support/topic/error-while-viewing-on-mobile-devices/#post-11605077) * I would need more details to troubleshoot your issue. * What is the shortcode you are using – include it here? * How have you specified everything in the shortcode, and on the site? * What type of image is in use? * The divide by zero error is because your image is failing to return a number for the php function getimagesize.

That worked however, i am curious why would something like that cause an issue? I mean i had the whole image path assigned. Thank you. * Another issue is the mobile image losses its parallax effect on mobile devices. Now, i sort of know this doesn’t work very well on mobile devices but is there any way you can make it possible using JavaScript or jquery. * Look at this example: [https://www.jqueryscript.net/demo/Responsive-Performant-Background-Parallax-Effect-Parallax-Background/](https://www.jqueryscript.net/demo/Responsive-Performant-Background-Parallax-Effect-Parallax-Background/) * Download: [https://www.jqueryscript.net/animation/Responsive-Performant-Background-Parallax-Effect-Parallax-Background.html](https://www.jqueryscript.net/animation/Responsive-Performant-Background-Parallax-Effect-Parallax-Background.html) * Plugin Author [thehowarde](https://wordpress.org/support/users/thehowarde/) * (@thehowarde) * [7 years ago](https://wordpress.org/support/topic/error-while-viewing-on-mobile-devices/#post-11605370) * This parallax effect doesn’t work on mobile. I am using a different parallax effect than the one you reference. * Glad your issue is fixed though. * Thanks 🙂 Viewing 10 replies - 1 through 10 (of 10 total) The topic ‘Error while viewing on Mobile Devices’ is closed to new replies. * ![](https://ps.w.org/parallax-image/assets/icon-128x128.png?rev=1627242) * [Parallax Image](https://wordpress.org/plugins/parallax-image/) * [Frequently Asked Questions](https://wordpress.org/plugins/parallax-image/#faq) * [Support Threads](https://wordpress.org/support/plugin/parallax-image/) * [Active Topics](https://wordpress.org/support/plugin/parallax-image/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/parallax-image/unresolved/) * [Reviews](https://wordpress.org/support/plugin/parallax-image/reviews/) * 10 replies * 2 participants * Last reply from: [thehowarde](https://wordpress.org/support/users/thehowarde/) * Last activity: [7 years ago](https://wordpress.org/support/topic/error-while-viewing-on-mobile-devices/#post-11605370) * Status: resolved
