# SyntaxError Error Message Tryign to Navigate WordPress

 * Hi,
 * I have the latest version of WordPress installed. I was able to log into wordpress
   yesterday and update pages no problem. I have not installed any new plugins or
   updated the core (already updated) and I am receiving the message below:
 * “SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON
   data
 * Gateway Anti-Virus Alert
 * This request is blocked by the Firewall Gateway Anti-Virus Service. Name: C99Shell.
   F (Trojan) “
 * Can anyone point me in the direction of what may be causing this…is it bad code
   in WordPress or is this on our firewalls end. Possibly a restriction that needs
   to be turned off? I see other people having this issue but not getting an answer
   that makes sense.
 * Thank you
 * BD

 * Have you discussed this with Gateway Anti-Virus Service?

 * Yes, we’ve figured this out as it’s a plugin that we have installed. My next 
   question to you is could this firewall gateway be stopping you from viewing the
   media gallery content when you are trying to add a featured image? All it does
   is spin and spin. And that is for all of our sites across our server, so it’s
   not a plugin.
 * Thoughts?

 * Hi ussailing,
 * We’re experiencing the same issue – multiple WP accounts affected, media library
   not loading because of SonicWall firewall blocking content…
 * Was this a false positive or is C99Shell F making a come-back?
 * Any help with this would be appreciated.
 * Thanks.
 * 🙂

 * Hi i’ve got nearly the same issue,
    Have you got a solution to fix that Problem,
   i think its a fault of the Provider?
 * Gateway Anti-Virus Alert
    Name: Suspicious#pbot_5 (Trojan)
 * Can help someone?
 * Best regards

 * Hi Gegun,
 * I can confirm we’re seeing exactly the same alert from our SonicWalls now…
 * I’ve already submitted this as a False Positive to Dell SonicWall and we’ve temporarily
   unselected the option in our devices to filter content for this particular signature.
 * I’d recommend that you still get in touch with SonicWall to discuss your particular
   occurrence of this problem, just in case yours isn’t a False Positive.
 * Hope this helps.
 * Warmly,
    Trojan-Webmaster
