Can't edit articles (Error decodin JSON data)

When I try to edit a article in Joomla I get the following error message:

Error decoding JSON data: Control character error, possibly incorrectly encoded

And in the error log it states the following:

Code: Select all

PHP Notice: Undefined property: stdClass::$moduleclass_sfx in /mysite.com/templates/gk_technews/lib/framework/helper.api.php on line 138

On line 138 in that file I see:

Code: Select all

if(stripos($params->moduleclass_sfx, 'gray-bg') !== FALSE) {

Do anyone know why this happens and how to fix it?

I use latest version of Joomla.

Hello.
I've updated joomla to 3.6.3 (gk_box_quickstart_J!3.zip). Now I have the same errors when I try to edit or create a new article (k2 or simple one) or try to go to virtuemart/shop:

An error has occurred.
0 Error decoding JSON data: Control character error, possibly incorrectly encoded.

Please see the attachment.

Hi

If this error is showing in administrator panel than our template has nothing to do with it. I think Your server configuration may not meet joomla requirements. Please report this to joomla developers or Your hosting support. https://www.joomla.org/about-joomla/tec ... ments.html

Hello,

TinyMCE editor causes the error. If you switch Default Editor (Global configuration) to "none" everything works properly. (Problem is visible only on servers with PHP 7.0.x)

The only solution for now is clearing "params" field (column) of tinymce plugins (plg_editors_tinymce) from jos_extensions table within your database. (remember about database backup before any changes)

Dear Joshua,

Thank you for help.

I've just changed TinyMCE to Editor-JCE (I use a server with PHP 5.5). It works!

Thank you for help Joshua M... i have same problem.

Hi

Ok. Looks like it's a good solution I haven't known that either. Anyway, closing this thread now.
