Update: The bug has been resolved in WordPress 2.5

This plugin fixes an issue that can cause several problems in the Administration Panel, including the following:

  1. The “You don’t have permission to do that” error when performing certain actions, even though you are in fact logged in
  2. The “Are you sure you want to edit this page: “”?” confirmation when trying to save a post or page
  3. Inability to remove pages or posts using the Management panels
  4. And possibly other problems that have similar symptoms

Most people who get these problems seem to be on a server that uses a hardened version of PHP. This version adds several security measures to PHP, including transparent cookie encryption. The WordPress function that checks whether you can perform certain actions in the Administration Panel (check_ajax_referer()) does not function properly because of this. This plugin replaces that function with a something that does take the cookie encryption into account.

Installation

After you’ve downloaded and extracted the files:

  1. Upload the complete ajax-referer-fix folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Verify whether the fix solves your problem

Frequently Asked Questions

Why do I need this plugin?

You only need this plugin if you are experiencing any of the perviously mentioned problems. If WordPress is working fine without it, then don’t waste your time on this.

Is this fix secure?

Short answer: Yes. Longer answer: The replacement function provided by this plugin uses the same validation method as the original function. There is one difference and it has to do with encrypted cookie data. I suggest you have a look at the source code (it’s commented) if you want to find out how it works exactly. The replacement function is no less secure than the original.

It does not solve my problem

You may be experiencing one or more of the previously mentioned problems for a reason unrelated to AJAX or encrypted cookies. In that case, this plugin is unlikely to solve it. However, it could also be possible that the plugin just isn’t perfect. In any case, it would be really helpful if you contacted me about your problem and providing the following information:

  1. Your PHP version (as displayed by the output of phpinfo())
  2. Hardened PHP Patch version (if any, try searching for ‘Hardened’, ‘Suhosin’ or ‘Patch’ in the output of phpinfo())
  3. The value of suhosin.cookie.encrypt (as displayed by the output of phpinfo())

License

The below text is out of date. Here is the current download link to the WordPress plugin, the advanced excerpt plugin. The plugin is still active, and many people are using (90K+), but the Plugin has not been updated for over 2 years.

This plugin adds several improvements to WordPress’ default way of creating excerpts.

  1. It can keep HTML markup in the excerpt (and you get to choose which tags are included)
  2. It trims the excerpt to a given length using either character count or word count
  3. You can customise the excerpt length and the ellipsis character that will be used when trimming
  4. The excerpt length is real (everything belonging to HTML tags is not counted)
  5. Possibility to ignore custom excerpts and use the generated one instead
  6. Theme developers can use the_advanced_excerpt() for even more control (see the FAQ)

In addition to keeping HTML markup in the excerpt, the plugin also corrects HTML that might have been broken due to the trimming process.

Version 0.2.1 adds support for multibyte characters (eg. Chinese and Japanese). This is slightly experimental, more details in the FAQ.
Plugin translations are fully supported and language files are included for translation. The FAQ provides more info on this, also.

Installation

After you’ve downloaded and extracted the files:

  1. Upload the complete advanced-excerpt folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Go to ‘Excerpt’ under the ‘Options’ tab and configure the plugin

Frequently Asked Questions

Why do I need this plugin?

The default excerpt created by WordPress removes all HTML. If your theme uses the_excerpt() to view excerpts, they might look weird because of this (e.g. smilies are removed, lists are flattened, etc.) This plugin fixes that and also gives you more control over excerpts.

Does it work for WordPress version x.x.x?

I haven’t had the chance to test the plugin on many versions of WordPress. It has been tested on 2.2 through 2.7, but it might work on other versions, too. You can safely try it yourself, because the plugin is unlikely to break anything (it’s only an output filter). Please let me know if you succesfully tested it on another version of WordPress.

Is this plugin available in my language? / How do I translate this plugin?

The plugin comes bundled with a few languages. The correct language will automatically be selected to match your WordPress locale.

More information on translation will be added in the future.

Does this plugin support multibyte characters, such as Chinese?

First of all, it should be noted that word-based excerpt length only works if your language uses normal whitespace as a word separator. If you use another language, you have to uncheck the Use words? option.

PHP’s support for multibyte characters is not perfect. The plugin provides support for these characters to the best of its ability, but there are no guarantees that everything will work.
Your best bet is to use UTF-8 encoding (which WordPress uses by default). If you still encounter problems, check with your host if the mbstring PHP extension is enabled on your server.

Can I manually call the filter in my WP templates, for example?

The plugin automatically hooks on the_excerpt() function and uses the parameters specified in the options panel.

If you want to call the filter with different options, you can use the_advanced_excerpt() template tag provided by this plugin. This tag accepts query-string-style parameters (theme developers will be familiar with this notation).

The following parameters can be set:

  • length, an integer that determines the length of the excerpt
  • use_words, if set to 1, the excerpt length will be in words; if set to 0, characters will be used for the count
  • no_custom, if set to 1, an excerpt will be generated even if the post has a custom excerpt; if set to 0, the custom excerpt will be used
  • ellipsis, the string that will substitute the omitted part of the post; if you want to use HTML entities in the string, use %26 instead of the & prefix to avoid breaking the query
  • exclude_tags, a comma-separated list of HTML tags that must be removed from the excerpt
  • allow_tags, a comma-separated list of HTML tags that are allowed in the excerpt

A custom, advanced excerpt call could look like this:

the_advanced_excerpt('length=320&use_words=0&no_custom=1&ellipsis=%26hellip;&exclude_tags=img,p,strong');

Does this plugin work outside the Loop?

No, this plugin fetches the post from The Loop and there is currently no way to pass a post ID or anything custom of that kind to it.
You can, however, consider to start The Loop manually.

Even if you’re already taking all the necessary precautions to maintain and protect your WordPress site, sometimes your site can still go down for reasons that you can’t control. You need to be prepared for when this happens in order to quickly put things back in order because the longer you wait, the more money you’re leaving on the table. Fortunately, there are a few nice website monitoring services and tools out there that will monitor WordPress uptime and downtime for you, so you don’t have to check it manually.

How does it work?

While you install it on your WordPress site, most of the action takes place in a separate dashboard provided by ManageWP, which monitors all of your sites in one place. So once you install the plugin, you need to go to your ManageWP account and add your site’s URL there.

Next, once things are all set, go to Uptime Monitoring and activate the add-on (it costs $1 per month for each site). You can then get notifications via:

Jetpack is quite similar to Orbit Fox. It is a multipurpose plugin that does a bit of everything, and helping you monitor WordPress uptime is one of those things.
