Hi there,

New to SilverStripe and new to the forums.

I just installed a fresh version of Silverstripe on top of Ubuntu/Nginx/PHP/Mysql and so far everything has worked perfectly except for the following:

When I go to load the page editor, the page fails to load the TinyMCE Editor and inspector shows the error:

Uncaught SyntaxError: Unexpected token < 


At the bottom of the page in the Javascript Includes area, there is an include attempting to load a .php file instead of a .js file and of course fails when the first line is "<?php"

<script type="text/javascript" src="/framework/thirdparty/tinymce/tiny_mce_gzip.php?m=1384281859&amp;js=1&amp;plugins=table,emotions,paste,media,fullscreen,inlinepopups,advimagescale&amp;themes=advanced&amp;languages=en&amp;diskcache=true&amp;src=false"></script>

Is this a failure on something else, or is there somewhere I can change it to load the .js file instead of the .php file.



Found a solution:

Under /framework/forms/HtmlEditorField.php i replaced the following block of code:

if(Config::inst()->get('HtmlEditorField', 'use_gzip')) {
                        $internalPlugins = array();
                        foreach($configObj->getPlugins() as $plugin => $path) if(!$path) $internalPlugins[] = $plugin;
                        $tag = TinyMCE_Compressor::renderTag(array(
                                'url' => THIRDPARTY_DIR . '/tinymce/tiny_mce_gzip.js',
                                'plugins' => implode(',', $internalPlugins),
                                'themes' => 'advanced',
                                'languages' => $configObj->getOption('language')
                        ), true);
                        preg_match('/src="([^"]*)"/', $tag, $matches);
                } else {
                        Requirements::javascript(MCE_ROOT . 'tiny_mce_src.js');


Requirements::javascript(MCE_ROOT . 'tiny_mce_src.js');

Thanks! I just had this same issue.
(Never had this issue before but am also using a shared hosting provider I've never used before)

I've had the same issue and I'm pretty sure it's an NGINX configuration issue, but since I'm not the best at adjusting NGINX config files I've come up with the following solution.

Instead of messing with the core Silverstripe files (by modifying /framework/forms/HtmlEditorField.php) like jonathanc suggested, it's enough to add the line below to /mysite/_config.php:

In Silverstripe 3.0:

HTMLEditorField::$use_gzip = false;

In Silverstripe 3.1+:

Config::inst()->update('HtmlEditorField', 'use_gzip', false);

The proper way to do that in 3.1+ is via yml (although _config.php still works fine - I'm just sharing a different approach).
eg. mysite/_config/config.yml

  use_gzip: false

For some reason this fixed my problem with tinyMCE's css files not loading properly. It was a sudden and unexpected break. The only thing that changed on my system is my MacOS updated to 10.12.6, though looking through it's changelogs I have no idea why that would be the reason for the error. Oh well. Thanks!
