When I try to access a couple of category blogs on my site I get:

 getting a 0 - Error decoding JSON data: Syntax error

Error. I turned on debugging and the result is in the attached image:

Error decoding JSON data: Syntax error

Call stack
# Function Location
1 Sh404sefClassRouterInternal->sh404sefExceptionHandler()
2 Sh404sefClassRouterInternal->sh404sefErrorPage() /home/phoeni81/public_html/administrator/components/com_sh404sef/classes/router.php:1997

Does any of this look familiar to you?

My site: xxxx.com/people

Thanks

Hi

1 - What are exact and full Joomla and sh404SEF versions running?
2 - Can you make a test and see if those categories can be accessed alright when sh404SEF is disabled?
3 - Anything special with those categories? ie not yet published? restricted access?
4 - What's the non-sef URL recorded for people in the URL manager? are there any duplicates? what are those duplicates if any?

1 - Joomla! 3.6.4 and sh404SEF 4.8.0.3423

2 - I 'm working on it.

3 - Nothing special. They've always worked and nothing has been changed outside of adding articles

4 - Non-sef is index.php?option=com_content&Itemid=1117&id=146&lang=en&layout=blog&view=category
One duplicate: index.php?option=com_content&Itemid=1117&id=146&lang=en&view=category

Hi

The problem here is that this error is probably actually not related at all to sh404SEF or even your content. What happens is that we have an exception handler that we use to catch errors generated by Joomla when something wrong happens, anywhere on the site (this allows doing our nice 404 error page even on Joomla generated errors).

So this json decoding error can be anywhere, in any plugin, modules, etc

1 - A start may be to go back to the category, check all parameters and save the setting again (settings are stored in json format)
2 - Another thing is to look at what has changed just before the errors started to happen (added/updated plugins, modules, template?) and try disable that and see if the page comes back up.
3 - You can also create a tempory link in the same menu, to the same category, with another name (and delete the link and the URL afterwards), just to know if the problem is more with the menu item, or with the category.
