Trying to "Mark site as read" from teh front end, I get the following error:

The CSRF protection key did not match. This may indicate a plugin or theme is out of date. Please contact technical support for more information.

Error code: 2S119/1

4.0.3 All plugins and theme disabled.   Ran through ACP help.

How do I fix my CSRF key?

I have the same problem, basically, when i Mark site as read it doubles the main link to the site and gets a 404 not found error and when i correct the link manually i get the CSRF error as described.

 

What i mean by doubles the link is this. notice in the example below how the main part of the site link is there twice.

what does the CSRF error even mean, and i notice the problem doesn't happen here or on my live 3.4 board on the same server.

I don't know what it means, other than my users can't mark the site read.   Hoping someone who does know, jumps in.

I know, and I've tried everything i know to do, i wonder if i can sent in a support ticket for this, since its technically on my test board. (getting ready to swap it with my live 3.4 board)

I have a bug report up about it, as it happened right after 4.0.2 to 4.0.3 upgrade, but so far I have not heard anything about how to fix it.

i fixed mine, i think. what i did was changed my php version to from 5.3 to 5.4 in my cpanel and enabled phar extension. (which also fixed another issue i was having)
