Concrete5 5.5.2.1 vs. mod_pagespeed from Google

Permalink
Hey C5ers!

I try to make mod_pagespeed work with the latest stable c5 version. Unfortunately the tip of the how to ("ModPagespeedDisableFilters trim_urls" -http://www.concrete5.org/documentation/how-tos/developers/how-to-ma... ) does not work anymore.

If I edit properties of a page in the sitemap view and try to save the following error appears:

Uncaught TypeError: Object function (d){var e=typeof d==="string",f=Array.prototype.slice.call(arguments,1),h=this;d=!e&&f.length?b.extend.apply(null,[true,d].concat(f)):
d;if(e&&d.charAt(0)==="_")return h;e?this.each(function(){var g=b.data(this,a),i=g&&b.isFunction(g[d])?g[d].apply(g,f):g;if(i!==g&&i!==j){h=i;return false}}):this.each(function(){var g=b.data(this,a);g?g.option(d||{})._init():b.data(this,a,new c(d,this))});return h} has no method 'showLoader'


Has somebody a solution for this? I experimented and disabled the "rewrite_javascript" filter but even that did not work. I'm kind of confused which filter causes the problem.

UPDATE:

I tested some more and now it seems to work (have more testing to do) with the following snippet:
<IfModule pagespeed_module>
ModPagespeedDisallow */concrete/js/*
</IfModule>
