* I created a post that had a lot of words (1000+) in it and tried previewing it
and got this error about memory:
* [http://disputebills.com/site/uploads/2015/06/Screen-Shot-2015-06-24-at-9.32.56-PM.png](http://disputebills.com/site/uploads/2015/06/Screen-Shot-2015-06-24-at-9.32.56-PM.png)
* I had a lot of plugins installed and tried uninstalling them individually. It
ended up being custom content shortcode that was causing the memory issue. I
disabled all other plugins and was still getting the issue. All I had was genesis
theme installed.
* I use this plugin for most sites I build on wpengine and have never had any issues
because their caching and server is so well built.
* I know I could fix the issue by changing the php.ini memory limit, but that doesn’t
seem like the right fix here. I only say that because at the time I didn’t have
any shortcodes being used on the site.
* Anyway, just wanted to post and see if anyone else was having issues with huge
posts.
* The page that this happened on is here:
* [http://disputebills.com/cutting-high-medical-costs-if-youre-uninsured/](http://disputebills.com/cutting-high-medical-costs-if-youre-uninsured/)
* I disabled the plugin so it now works.

* Thank you for posting about the issue. It’s the first time to hear about it –
there were a couple of people who mentioned that having a large number of posts(
~5000, I think it was) slowed down the queries/page load, but that’s true in
general.
* > ..at the time I didn’t have any shortcodes being used on the site
* This is an interesting point: if the plugin wasn’t doing any work, then it means
there’s a memory issue only from being loaded..?
* In the plugin settings, could you try turning off all modules one by one to see
if any of them are directly related? For example, the [raw] shortcode by its
nature needs to parse the post content, which could be memory intensive.
* Also, the plugin Query Monitor could be helpful in showing a stack trace of the
error, to see where it originated.
* Meanwhile, I’ll try to recreate the issue on my end to analyze where it could
be happening.

* Hey thanks for the reply Eliot. I backed up the site so I could try it on WPENGINE
because I know it will work there.
* When this originally happened, Query Monitor was actually the first thing I checked,
but since the page was “cashing out” before it was able load all the way, the
Admin Bar and Query Monitor wouldn’t load.
* Anyway, WP-ENGINE lets you create sandbox servers, so I’m going to try and recreate
there. I’ll let you know when I do and can give you login access if you want
to check it out so you don’t have to waste your time trying to recreate. Just
let me know.

* Hey Eliot I got to the bottom of it. I created a sandbox on WPENGINE and transferred
over the .sql database file from the GoDaddy site. To my surprise it didn’t work
there either and was bringing me to a 502 error page.
* So I took the same steps I did on GoDaddy and I disabled all the plugins, then
the genesis child theme, then genesis, and all the plugins. Still no luck.
* The fatal error logged in the debug for exhausted memory occured on one of three
lines below each time the page would load
* ```
wp-includes/shortcodes.php on line 200
wp-includes/shortcodes.php on line 227
wp-includes/shortcodes.php on line 196
```
* In the backend, while updating the post, query monitor would report [this](http://disputebills.com/site/uploads/2015/06/Screen-Shot-2015-06-27-at-6.49.20-AM.png)
* Since this whole time I’d thought it was too long of a post I decided to see
how many words I could actually have before it broke, but not even that helped!
I only had a paragraph left and it still broke.
* Anyway, I switched to html mode and caught it right away. I wish I had done that
earlier…
* **This was the second sentence of the article:
* [The study, published in _Health Affairs_ scientific journal](http://content.healthaffairs.org/content/34/6/922.abstract[content.healthaffairs.org]),
found that 50 US hospitals were charging an average of 10 times the actual cost
of providing care to their patients.
* **But when looking at it in html mode, the comment you quoted me on about having
no shortcodes caught my attention :
* `The study, published in Health Affairs scientific
journal, found that 50 US hospitals were charging an average of 10 times
the actual cost of providing care to their patients.`
* I’ll tell the owner of the website to try to find a different link to point to
because I know urls aren’t suppose use square brackets. However, what do you
think the odds are that we can fix this with custom content shortcode, since
it allows shortcodes to be used in urls?

* Ahh, I see, it’s interpreted as `[content]` which shows the content of the current
post, which then runs it again, in an infinite loop. I actually came across this
problem before – someone just put `[content]` in a post, which ran itself endlessly.
I’ll work on a solution to detect this situation and stop it from happening.
* I’m not sure if there is a way to prevent accidental shortcodes. The difficulty
is that square brackets are fairly common to use, and that’s a fundamental design
problem of shortcodes. The strange thing I see above, is that there is no closing
square bracket `]` – so it looks like it shouldn’t be interpreted as a shortcode.
* A couple related points.. There is a `[direct]` shortcode, which can be used
to disable shortcodes inside itself.
* ```
[direct]
Here, shortcodes like [content] are displayed directly, without running.
[/direct]
```
* Another point is about the _escape_ parameter for fields. When using a field
value in an HTML attribute like a link, this will prevent issues if the value
contains special characters like `"` or `&`.
* ```
```
* Anyway, I’ve started on a solution to prevent infinite loops, and will include
it in the next update. Thanks for the information.

* OK, I just made a plugin update so `[content]` will detect if it’s showing the
current post already, and show a warning if there’s an infinite loop happening.
* Yes, I see the link ends with `[content.healthaffairs.org]` which was causing
the issue. You’re right that `[` and `]` are not valid characters for URL and
should be escaped.

* Glad we got this figured out quickly. Thanks again for the quick responses. You’ve
really done a great job with this plugin. Reminds me a lot of [Timber](https://wordpress.org/plugins/timber-library/),
but way more convienent for wordpress. I’ve actually been taking some ideas from
[https://github.com/cftp/shortcode-suggest](https://github.com/cftp/shortcode-suggest)
and [http://gndev.info/shortcodes-ultimate/maker/](http://gndev.info/shortcodes-ultimate/maker/)
the last month and am making an addon for custom-content-shortcode, that would
give us a custom post type for the templates with autocompletion and an insert
button on the post editor. I’ll let you know how it goes!

* Wow, first add-on for the plugin, cool! Curious to hear how it turns out. I’ve
been using the front page of the plugin references as a place to put announcements
and notices. I can put a link to your add-on there so people will know about
it.
