go to your wp-config file and search for the below code and change false to true and repost the error message here
/**
* For developers: WordPress debugging mode.
*
* Change this to true to enable the display of notices during development.
* It is strongly recommended that plugin and theme developers use WP_DEBUG
* in their development environments.
*/
define(‘WP_DEBUG’, false);
Can you provide a little more info? I see content, so I don’t know what you’re referring to exactly.
Put down all the detail you can about your hosting environment, your WordPress install (plugins, themes, etc.) and the problem you are having. If you are seeing errors, copy them word for word into your post. It’s best to include the full error than to summarise – sometimes wording is important. If you did something before you came across a problem, write down exactly what you did.
I guess this comment fits into this thread. I normally park my pdf files in my media library and link to them from my pages. It always worked fine. I have been doing this for years. Suddenly after upgrading to WP 3.9.2 the pdf files ALL disappeared. The titles are there with links but nothing can be viewed. The pdf files are gone. I had no warning about this and I have no idea why it happened.
I have tried for a very long time to back up my media gallery. With all of the hoopla about backing up the database, or exporting an XML file, the media are always ignored. I installed a plug-in that explicitly said it would back up the media. After using it, I discovered that it would not back up the pdf files, only the jpg files. I asked the developer about this and he said he would fix it but never did. However I don’t know if a backup would have helped. It is as thought WP just doesn’t recognize the pdf files any more.
My two websites are http://www.greensocialthought.org and http://www.zerowasteinstitute.org. There is no error message at all. The pdf files are just not there.

Further information on the missing pdf files. I uploaded a new pdf file to the Media Library and though it seemed to upload normally, it was no more visible than the older pdf files.
I took note that pdf files are allowed to be placed in the MEDIA LIBRARY according to the official description of the library, which lists the kinds of files to expect and includes pdf files. See
http://codex.wordpress.org/Media_Library_Screen#Table_of_Media
So I’m not trangressing any rule by expecting a pdf file to be linkable in the Media Library.
I’m out of business until I can solve this problem.
I can’t be the only person with this problem.
What is going on?
Thank you for some help.

A temp work around would be to upload to a folder on your server and create links to the pdf files. You are not the only who seems to be having this prob, if you are not seeing error messages or warnings try turning on debugging mode temporary and re- upload a pdf file and see if any warnings or errors show up, since upgrading to the new word press one common error message with different references kept showing up, {Fatal error: Internal Zend error – Missing class information for in ………/wp-content/plugins/wp-super-cache/wp-cache-base.php on line 5} and “Disabling APC on Your Hosting Account” seems to solved it in each case even thou each person had different problems.
