Visual Editor in 2.5

azaozz (and everybody else), thanks for all of your help.

i was having the blank pop-up problem, and installed azaozz’s testing tinymce plugin, but was still getting the blank pop-up, even after clearing every cache i could get my hands on, restarting firefox, and waiting 5 hours.

finally i right clicked on the blank pop-up and chose the ‘reload this frame’ option and it showed up and is working fine now. the ‘reload..’ option is no longer showing up after the fix though.

I bet clearing the caches and waiting a few hours helped too ??
All caches tend to hold on old js and css files as they don’t change often and force-reloading the pop-up iframes (even several times) will eventually make all caches between you and your site refresh.

After a bit of digging I have determined that my problem is caused by the plugin WP-ContactForm, specifically, the use of the Buttonsnap Class Library (buttonsnap.php) which adds a custom button to the tinymce editor. I suppose I will need to find a new plugin as I do not have the means to try and fix it.

There is a reference to this problem here:-

I discovered the problem also goes away if I add the line zlib.output_compression = On to php.ini.

Edit: Not only does the visual editor begin working again, it does not display the custom buttons from buttonsnap.php (but I have another plugin, wordtube, whose button /does/ appear).

Hi. I have two WP sites ( https://bellasvenezolanas.org and https://hotbellasvenezolanas.org), and after I made the upgrade from WP 2.3.3 to WP 2.5, in https://bellasvenezolanas.org I can′t use the Visual Editor in the “Write” and “Manage” posts… I can only have the html feature on, and I can′t change to Visual… In my other it works fine. And it′s the same on Firefoz and IE…

chaz6, adding zlib.output_compression = On to php.ini will compress all output by default. This is the proper way to use it. TinyMCE’s compressor detects this and doesn’t try to compress the js, so the double compression problem goes away.

All plugins that add buttons to the editor in 2.3 (TinyMCE 2.x) will most likely fail in 2.5 (TinyMCE 3.0). Some can break the editor, some just wouldn’t work until they are updated.

Question: What is this “double compression” problem? I ask because WordPress has had the gzip compression removed from it. TinyMCE still has compression in it, but I don’t see what’s doing the second compression stage here.

I copied again all the WP files in my server, I turned off and turned on the plugins, I placed my PC upside down, and did everything, and still can get into the Visual Editor, neither with IE or Firefox…

And I can’t get into the Widget menu in the WP Admin…

There are several ways to compress output from the web server if the browser supports it (all newer browsers support that). Apache has a deflate module and php can use zlib. This can be enabled by default for all output in php.ini, or by setting the output buffering.

Apache’s module works well as it runs after php has finished and doesn’t try to compress already compressed output. However if php uses compression and it’s not set in php.ini (zlib.output_compression = On), it may try to double compress the already compressed TinyMCE + all plugins js file.

bellasvenezolanas, this is most likely cache problem. May have to wait it out until all network caches between you and your site have refreshed. Force-reloading the affected pages (by holding down Shift/Ctrl) may speed this up, depending on the caches.

Where’s the php.ini file?

1. Compression is enabled on the server. If it’s set properly (in php.ini) the compressor for TinyMCE would detect it and not try to compress the js. To check for double compression: with Firefox, go to [your-site]/wp-includes/js/tinymce/tiny_mce_config.php. Should be a large text (js) file, starting with “var tinyMCEPreInit = …” and last line starting with “tinyMCE.init({mode:”none”,…”.

If it’s not – edit tiny_mce_config.php, looking for
‘compress’ => true,
change to
‘compress’ => false,

or if preferred, download this small plugin that will disable caching and compression when active:

The plugin works! Now I get back the Visual Editor! Thank you, azaozz!

I was having the same problem as many with the Visual Editor in WP 2.5. I cleared the cache in all browser types: Firefox, IE, Opera and Safari and was still having the same problem. I even called my host to make sure everything was what was needed). I was able to fix (or work around) the problem by doing the following:

1. I installed the plugin: TinyMCE Advanced.
2. After installing and activating the plugin. I again cleared the cache. Closed and reopened the browser. Then after logging in and opening a post to edit I had to again refresh.

– Presto.. It’s working! I can add links!

Hope this may help others.

Tried azaozz’s plugin and that seemed to do the trick. Thanks!
