Bug report and fix for config file "Exception in loadConfig for unserialize"

[omniroot]

I just did a fresh install of Joomla 3.3.1, and installed VirtueMart 2.9.6 from the archive file on the virtuemart webpage.

I ran into an error after saving the virtuemart configuration, where I would see the message:

Exception in loadConfig for unserialize __utmz s:69:"88103696.1403146316.1.1.utmcsr

To avoid this message, enter your virtuemart config and just save it one time

Exception in loadConfig for unserialize utmccn (direct)

To avoid this message, enter your virtuemart config and just save it one time

Exception in loadConfig for unserialize utmcmd (none)";

To avoid this message, enter your virtuemart config and just save it one time

After much searching through the code, and using chrome's dev tools, I figured out what the problem is:

the __umtz, utmccn, and utmcmd variables were stored in a cookie for my site.

In the VirtuemartControllerConfig controller at administrator/components/com_virtuemart/controllers/config.php, near the top of the save function, there is a line:

Code Select Expand

$data = vRequest::getRequest();
But all of the data we need is being sent through the form as POST data, so why are we using getRequest() that will fetch cookie data as well?

We should change this line to:

Code Select Expand

$data = vRequest::getPost();

and the issue will be fixed.

I have tested this on my install, and the fix was successful.

Please path this in the next release.

Also, can someone please email me about contributing these types of fixes to virtuemart development?

Thank you,

Hartley

On VM 2.9.8 Joomla 3.3.1 this bug appears to be back again:

I get the following error whenever I enter my shop (frontend) or virtuemart backend:

Code Select Expand

Exception in loadConfig for unserialize __utmz s:70:"181814309.1404249068.1.1.utmcsr
To avoid this message, enter your virtuemart config and just save it one time
Exception in loadConfig for unserialize utmccn (direct)
To avoid this message, enter your virtuemart config and just save it one time
Exception in loadConfig for unserialize utmcmd (none)";
To avoid this message, enter your virtuemart config and just save it one time

I have ofcause tryed to save the config several times.
