Hi Terbium,
It looks like you have a JavaScript error on that page: TypeError: a.cookie is not a function which is coming from a script loaded by WooCommerce.
This gallery demo, which is running WordPress 4.4 and the latest version of WP Featherlight, should confirm that there are no conflicts with WordPress 4.4 and WP Featherlight.
I think there must be an issue with one of your other plugins or your theme. Try disabling WooCommerce and see if the issue is resolved. If not, I’d recommend disabling all other plugins on the site and then re-activating them one-by-one until you find the source of your JS error.
If that still doesn’t work, try switching to one of the WordPress default themes and see if the error persists.
Hey Terbium,
Have you tried WP Featherlight with the TwentyFifteen theme active and all other plugins disabled?
We’re seeing several JavaScript errors on your site and any issues you’re having are probably related to those https://cloudup.com/cl9XES9WBTd
You may specifically look to see if any other plugins are loading lightboxes. I know that WooCommerce has a lightbox that may be conflicting.
Once you’ve had a chance to test the way I described above, get back to us and let us know if you’re still having issues and we’ll be happy to help.
Thanks
Thanks for your quick answers. I deactivated my extensions (except Featherlight) and the website can’t show up. I get this message:
Fatal error: Call to a member function plugin_url() on a non-object in /home/raoul372/public_html/phototrope.ca/wp-content/themes/twentytwelve-child/functions.php on line 19
Hey Terbium,
It sounds like your theme is calling a custom function from one of the plugins on the site. The function plugin_url is not part of WordPress core, so that’s why you’re seeing an error with your plugins deactivated.
You’ll need to either figure out where that function is coming from and re-activate that particular plugin, or make sure the function exists by using a function_exists check before using it in your theme.
I reinstalled all my plugins, even WooCommerce which I don’t use anymore. I know that every time WooCommerce is updated, I have to modify its js assets. For whatever reason, the files jquery-cookie.js and jquery-cookie.min.js have to be changed to jquery_cookie.js and jquery_cookie.min.js.
I’m not sure if it’s related to my problem (I’m not a programmer). All I know is that now my site is completely screwed up… It seems that if I want to get rid of WooCommerce and its translation plugins, my site doesn’t work even if Woo Commerce is on hidden pages. Sigh.
Hey Terbium,
We’d love to help you get this sorted out, but without some additional info we’re going to be a little bit stuck in terms of what we can do.
We offer a code review service that will help identify some of the most obvious issues in your theme/plugin setup and configuration and will help you stabilize the site quite a bit.
If you’d be interested in some additional help that way, we’d be happy to take a look at it for you. You can reach us direct at http://www.wpsitecare.com/contact/ for some more 1 on 1 help.
Thanks
Thanks for your offer. But I think I’ll rebuild my site from scratch without WooCommerce. My site used to work well but I’ve lost hope to sell my photos online… Also there are probably conflicts between my other plugins. On top of that, creating a bilingual site doesn’t help. I’m really tired of seeing my site suddenly breaking down and having to spend days trying to figure out why. Anyway, thanks again for your help. And Merry Christmas!
I don’t get it. I reinstalled everything and purged W3 Total Cache and now everything works fine, even Featherlight. Until the next crisis…
Happy New Year!
Glad to hear it! Happy New Year to you too. Good luck!
