Exception: SyntaxError: JSON.parse: unexpected character

Recommended Posts

While attempting to edit CSS in the default skin, I get this error and edits will not save. Can anyone help? I cannot edit anything in the skin editor.

@AIWA - Thanks for the suggestion. I disabled mod_security via .htaccess using

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off


That did NOT resolve the issue.

I then disabled it server-wide by recompiling Apache (using EasyApache 3.22 in WHM) Because this is on a VPS server that I manage I was able to update Apache and disable mod_security serverwide. This fixed the problem, however I am not sure what the full implications of disabling mod_security will be for other accounts, scripts and apps running on this server. Probably not good. For those who use shared hosting and do not have access to modifying Apache, good luck convincing your host to disable mod_security.

If someone knows what the actual problem is, that would be helpful. Thanks again AIWA for your suggestion.

The issue is a rule / setting within mod_security. This isn't an IP.Board issue. It's mod_security intercepting the save request with the template data and throwing an error.

That is the 'actual problem'.

You'll need to work with your host / server administrator to identify the mod_security rule that's causing the issue and either disable that rule, or make just that rule / setting more lenient.

As this is server related, and not skin related. I've moved it to a more appropriate forum for you.
