Hello @mcaldex!

This is your first pull request on statsdata repository of the PrestaShop project.

Thank you, and welcome to this Open Source community!

@kpodemski hi, I hope this makes sense.
Would be great to LGTM #37 also :)

thanks

anyways, at the end of the day, this fixes only the insertion of some Guest's properties such as:
screen_resolution_x, width, screen_resolution_y, adobe_flash etc.

I'm not sure it those properties are useful anyways, but this still fixes the error in the browser's console which is the main reason I digged a bit and found this issue on my prestashop.

@Touxten @Quetzacoalt91 hey, lmk what you guys think.
Should we rather fix the loading of this js plugin when the PS_STATSDATA_PLUGINS configuration is enabled, or completely remove it from the module?

The changes look good to me, however it would be better to have an issue first to confirm there is an issue to fix.

Hello @mcaldex,

I tested your PR but I have somes problem. I don't found the error "Uncaught ReferenceError: PluginDetect is not defined" with or without your PR. And with your PR, when I inspect the code I don't found plugindetect.

Did I miss something?

Thanks!

Hi @paulnoelcholot , that's because the error will show up only if there's no id_guest set in the cookie, thus it will only appear on the very first time you open up the frontoffice with your browser.
Please try to go incognito every time you need to test it out and open the console, lmk thanks :)
