modernizr bugged on chrome

[PowerChaos]

hi all this is a strange bug report , but it only happends on google chrome browsers ( latest version ) please see attached video , this is taken from the latest prestashop , but the bug also exist in here

here is also a small snipped for the bug report

ok it seems it is heavy related to google chrome and its behavior ( and how sensitive it is to javascript i guess ) if i test it on other browsers then it seems to act just fine (coulnd reproduce the bug )

also in chrome it doesnt show the dropdown ( sidebar ) like it does in internet explorer or in Edge

if you click in edge on the setting ( like shop parrameters ) it shows a dropdown in that list like on mobile vieuw in chrome , it just does not shows a dropdown at all , and if it doesnt trow that error it shows the hover

Tested versions below Chrome version : Versie 64.0.3282.167 (bug reported version ) latest version : Versie 64.0.3282.186 ( bug still exist )

Not able to reproduce the bugs (it does not exist ): Internet explorer : 11.25.16299.0 internet explorer update version : 11.0.49 Microsoft EdgeHTML 16.16299 Microsoft Edge 41.16299.15.0

Hi,

sorry, but this request is for PrestaShop 1.7 and this version is very different.

If you can reproduce the bug with thirtybees, come back with information about this trouble.

its exactly the same , tested it on the thirtybees demo site before i even made this bug report as i hate to work with other browsers ... and it really breaks things a lot

unless that site does not use modernizr anymore from prestashop ( so there own fully modified version ) will this error still exist

just to confirm everyhting , i only needed to enter the backend demo and i got the error already Uncaught TypeError: Cannot read property 'insertBefore' of null at a.yepnope.injectJs (modernizr.min.js:4) at modernizr.min.js:4 index.php?controller=AdminDashboard&token=98750039237cd341cc6635569addf7bc:1 Slow network is detected.

Hi,

i think your trouble come with your browser configuration and extensions.

I made test and i don't see any trouble, but i don't have any extensions to put code on my visiting sites.

desable every extension on your browser to make a test.

@Mediacom87 ok it does seems related to a browser plugin

specialy the following plugin poperblocker ( popup overlay blocker )

if i disable or remove it then the bug does not happen

so its more a extention bug then a script bug ? is it possible to rewrite modernizr so it can prevented , as i am definaly not the only one with that extention

i shall make a bug report to the creator of that plugin so he can also adjust his code to prevent this from happening

Thank you for your response and the solution :dark_sunglasses:

Likely something in the extension library conflicts. I would report it to them.
