Title: PHP 5.3.6 breaking javascript? Last modified: August 20, 2016 --- # PHP 5.3.6 breaking javascript? * [krispy_b](https://wordpress.org/support/users/krispy_b/) * (@krispy_b) * [14 years, 10 months ago](https://wordpress.org/support/topic/php-536-breaking-javascript/) * All of my WordPress installs on my windows 2003 server have javascript errors( both in jquery and tinymce), causing the editing post/page window to show in a ‘plain’ form, with mosst of the functionality broken. * the FIRST error shows below – with it pointing at the first \” escaped quote? later errors show jQuery not defined, and tinymce not defined – all appears due to the javascript not parsing; * **Error: illegal character** Source File: [http://www.dev-decor.co.uk/wp-admin/load-scripts.php?c=1&load=jquery,utils&ver=7bb5fde83e0949a753f31e184d1c6ac7](http://www.dev-decor.co.uk/wp-admin/load-scripts.php?c=1&load=jquery,utils&ver=7bb5fde83e0949a753f31e184d1c6ac7) Line: 16, Column: 77 Source Code: (function(E,B){function ka(a,b,d){if(d===B&& a.nodeType===1){d=a.getAttribute(\”data-\”+b);if(typeof d===\”string\”){try{d =d===\”true\”?true:d===\”false\”?false:d===\”null\”?null:!c.isNaN(d)?parseFloat( d):Ja.test(d)?c.parseJSON(d):d}catch(e){}c.data(a,b,d)}else d=B}return d}function U(){return false}function ca(){return true}function la(a,b,d){d[0].type=a;return c.event.handle.apply(b,d)}function Ka(a){var b,d,e,f,h,l,k,o,x,r,A,C=[];f=[]; h=c.data(this,this.nodeType?\”events\”:\”__events__\”);if(typeof h===\”function\”) h= * I thought my upgrades to 3.2 had caused an issue (that or installing wincache php extension which i’ve since disabled), but I have a single 3.14 wordpress blog on the same server, which shows exactly the same symptons – all were working before i upgraded the PHP to 5.3.6 to enable me to upgrade to wordpress 3.2. * so I believe the problem (and others may be having it too), is that the PHP 5.3.6 version with WordPress is causing issues with the javascript files that are used? * another website I run on the server which I wrote myself, which also uses tinymce is working and displaying the editor fine – so it’s def something to do with how wordpress is using those javascript files? * please dont’ tell me to turn plugins off in my 3.2 upgraded sites, because the 3.14 site I’ve not touched in any way has broken overnight, at the time i upgraded php.

I didnt’ think it would make a difference, as I said, the 3.14 untouched workdpress install is broken, and the only change is the new version of php in the environment. * when I get time (tomorrow earliest) i may try a vanilla (no plugin) install within a sub directory of one of my domains on the server, to see if the same issue occurs there – my guess is yes. * the issue seems to be the javascript files getting written out differently – causing the browser to error? * firefox is pointing to the first \” in the javascripts as the problem? * /*! * jQuery JavaScript Library v1.4.4 * [http://jquery.com/](http://jquery.com/)** Copyright 2010, John Resig * Dual licensed under the MIT or GPL Version 2 licenses.* [http://jquery.org/license](http://jquery.org/license) * * Includes Sizzle.js* [http://sizzlejs.com/](http://sizzlejs.com/) * Copyright 2010, The Dojo Foundation* Released under the MIT, BSD, and GPL Licenses. * * Date: Thu Nov 11 19:04:53 2010 -0500 */ (function(E,B){function ka(a,b,d){if(d===B&&a.nodeType===1){d=a. getAttribute(\”data ^ * firefox also mentions charset is UTF-8 if that’s of interest * [Andrew Ozz](https://wordpress.org/support/users/azaozz/) * (@azaozz) * [14 years, 10 months ago](https://wordpress.org/support/topic/php-536-breaking-javascript/#post-2169232) * Try adding `define('SCRIPT_DEBUG', true);` to wp-config.php so you load the non- minified JS files. * > the FIRST error shows below – with it pointing at the first `\"` escaped quote? * Yes, seems something is adding `\` chars to the JS files that shouldn’t be there.

Not good. * SCRIPT_DEBUG forces the non-minified JS files to be loaded separately (it turns off concatenation too) so there is some delay especially on high latency connections. However that affects mostly the admin, not the front-end.
