Galleria theme occasionally not loading

Question

I am using the Galleria slideshow on my site, but I've noticed an error that seems to happen very randomly. Most of the time the slideshow loads correctrly but once in a while I get this error:

 Uncaught Error: Fatal error: Theme at javascript/themes/classic/galleria.classic.js
 could not load, check theme path.

When I reload the page, it's all back to normal. This is the code I'm using to load it:

  <script> 
        // Load the classic theme
   Galleria.loadTheme('javascript/themes/classic/galleria.classic.js');
    </script> 

I have searched around but still haven't found a solution that works. My personal idea was to have a script that keeps loading until it succeeds, since on reload the page works. How would I do this?

Answer 1

1 Try the latest build at gihub: https://github.com/aino/galleria/blob/master/src/galleria.js

2 Try loading the theme using a script tag instead:

<script src="javascript/themes/classic/galleria.classic.js"></script>

Answer 2

I adopted the method pointed out by David, loading the theme using a script tag:

<script src="javascript/themes/classic/galleria.classic.js"></script>

But was eventually getting another error (Fatal error: Theme CSS could not load after 20 sec). I'd also recommend adding the CSS using a link tag:

<link rel="stylesheet" type="text/css" href="galleria/themes/classic/galleria.classic.css" />

I had a similar message today when I tried using Galleria. It happened only in Firefox. What I did to get around it is to add the theme stylesheet link directly in the head. I kept the theme script link in too, after the stylesheet, just in case it was needed. After that, the error message went away and Galleria is working as it should.
