 * Hi, Mr. Nickboss! First of all; great plugin. The best I could find. Love the
   minimal layout of it as well as its simplicity.
 * Yet, of course (or I wouldn’t be here), I came across a small but significant
   problem; when a visiter uploads an image, lets say a jpg, he or she gets an error:
 * “File succesfully uploaded but with errors.”
 * followed by
 * “Warning: JSON parse error.
    Upload parameters of this file, passed as JSON string
   to the handler, could not be parsed.”
 * So, what am I doing wrong and even better; do you have a solution for me? Thanks
   in advance for your reply!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwarning-json-parse-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi, strange error. Can you please send me the shortcode to check? Furthermore,
   what is the URL of the page to try myself?

 * Hi Nickolas. Thanks for your reply. The page where the error(s) occur is: [https://www.eamel.net/blog/dirkjan/](https://www.eamel.net/blog/dirkjan/)
 * The weirdest thing is; I’ve tried to upload a jpg in three (!) different browsers.
   Chromium + Chrome, which are stuffed with extensions so one would expect there
   is a extension which blocks the process but when I do the same thing within the
   Firefox browser, which has no add-on at all, it still gives the same error.
 * As said, the error (partly Dutch, tried to translate it ;-)) to be seen is:
 * “Bestand gescand_02_40.jpg succesvol geüpload but with warnings
    Warning: JSON
   parse error. Upload parameters of this file, passed as JSON string to the handler,
   could not be parsed.”
 * I’ve been through all the settings of your plugin and also installed a new version
   of javascirpt on my pc. There might be a possibility another plugin blocks it
   from uploading but I can’t imagine that is the case. I also changed the permissions
   thorugh FTP but, again, that didn’t work.
 * So, I can’t get my head around it, I’m afraid. Thanks in advance for your effort.
 * Greetz, eamel.

 * Hi Greetz, looking at Javascript Console, I see some errors related to Audio 
   Player plugin. Can you disable it to see what happens? Maybe it is causing the
   JSON error.

 * Nope. Unfortunately that wasn’t it. ;-(

 * There is also another plugin installed, Youtube Embed Plus. Can you also try 
   to deactivate it and try again?
