CSS JS Loader [Support Thread]

[DrByte]

I always avoid using the "CSS/JSS loader" plugin, because it's always made it harder to support or upgrade every site I've ever seen it on.

I've never found any legitimate reason for it to be needed, except that some plugins "require" it for completely unnecessary reasons.

Zen Cart loads JavaScript alphabetically. It has no ability to control library dependencies and therefore you'll get plugins loading before the main jQuery library or duplicate versions of jQuery loading. Our plugins that use jQuery require CSS JS Loader for this reason.

Given that they are loaded alphabetically it's quite easy to control load-order just by naming the files accordingly.
Plus, in v1.5.5 jQuery is loaded before any other jscript_* files, so that dependency is already taken care of, leaving very few other load-order issues that would need managing via filename.
Far simpler to manage in my experience.

who knew??

i too have experienced the headaches associated with load order and problems with CSS/JSS loader. i too find it rather difficult to maintain....

perhaps when i have time, i will now pull it out from some clients sites. troubleshooting JS load problems is always a pain, and once i have things working, i'm always hesitant to start fiddling and make it "better".....

It can be difficult for those used to the way Zen Cart does it. The problem is that so many template-builder websites use their own way and not the Zen Cart way, so they scatter their stuff everywhere.

CSS JS Loader also adds a minify option, browser-specific CSS/JS, and support for meta fields. Our clients that use it are using only plugins that are compatible with it, which makes it a lot easier to manage. Third-Party plugins that use Zen Cart's default system are fine as well. When a file has the same name, it's not duplicate loaded. Many of our clients have high traffic websites with orders coming in every few seconds, so having the speed optimizations offered by this plugin are very important.

i am still a big fan of the loader

Hi

I installed CSS JS Loader in my V155d with the green classic template on my non-SSL xampp test site.
Installation seemed to work OK, I got the "loader installed" message at the top and I can configure the loader in the Admin configuration but my storefront does not open.
Earlier I had it installed on my v154 site where it was OK

I got the following Log message but I have no clue what it is telling me

OK, did some more research.
I am running this on my non SSL xampp test site PC.

My Admin site opens fine after installing the CSS JS Loader but when I try to open the storefront I get the error message "PHP Notice: CURL error checking plugin versions: 60:SSL certificate problem: self signed certificate in certificate chain"

This message I discovered is an SSL Cerificate failure, but I do not want or have SSL on my test store front.

My includes/configure.php is unchanged, copy below, and worked fine on my test site before installing the CSS JS Loader. Only since installing CSS JS Loader do I see the SSLproblem.
My admin/includes/configure.php file must be correctly set to non SSL because the admin site opens fine!

I am using v155d and the responsive classic template
What else could be triggering SSL certificate request? Or where should I look?

It's the CSS/JS Loader attempting to see if an update is available.

Use your admin's Tools->Developers Tool Kit to search for plugin_version_check_for_updates in all files to locate the instance associated with the CSS/JS Loader and simply comment-out that function call.

On the principle of trying everything I tried deleting the "define('HTTPS_SERVER', 'https://localhost:8080');" in the configure.php but it did not help.

You are a star, that fixed it :)

Many thanks

Thanks for the compliment, but note that what I provided is a work-around, not a fix! To actually correct the issue (and enable your XAMPP installation to run in SSL mode), check out this Zen Cart posting: https://www.zen-cart.com/showthread....er-certificate
