Try changing the line

Code:

$blnIsOpen = ($session[$node][$tid] 1 || count(preg_grep('/^' . preg_quote($currentFolder, '/') . '\//', $this->varValue)) > 0);

to

Code:

---

$blnIsOpen = ($session[$node][$tid] 1 || count(preg_grep('/^' . preg_quote($currentFolder, '/') . '\//', (is_array($this->varValue) ? $this->varValue : array()))) > 0);

hey,

I have the same problem. I changed the line, but it didn't work :(
the error still appears. what else can I do?
please help

Hello,

which PHP version do you use? I had this error message when using PHP 5.1 while Contao needs 5.2 as minimum requirement.

Hello there.

I also got this problem.

I tried to change that line — without any success.

And on my server it's PHP Version 5.2.17 running.

It's quite likely that there's some uncaught exception causing output in the AJAX response. How can I debug the AJAX requests, maybe with FireBug?

So folks.

Using the network tab of FireBug you can check all site's XHR traffic. I opened the tab and then clicked to expand the folder.

I saw the request in FireBug and checked the answer.

And as expected it's returning a PHP error:

Code:

---


Fatal error:  Out of memory (allocated 31457280) (tried to allocate 2953 bytes) in …/system/libraries/Controller.php on line 1026

---

In my case the problem was a picture in the folder with the size of 2053 x 1965 px².

When listing images (both in the back and the frontend) Contao is generating a thumbnail for the file list as well as for f.e. galleries.

Generating a thumbnail is quite memory consuming.

Contao got the following settings

Code:

---

$GLOBALS['TL_CONFIG']['gdMaxImgWidth']
$GLOBALS['TL_CONFIG']['gdMaxImgHeight']

---

to control which images to try to resize. Their default value is 3000.

I needed to change this setting to a lower value. This value depends on the memory that your provider is offering.

Does this help anyone?

After the Update I got almost the same Problem - Parse Error when I wanna open a Folder...

Just checked with the network tab of FireBug - XHR traffic and got this one here:



Fatal error: Call to undefined function json_encode() in /var/www/vhosts/tssports.de/httpdocs/system/modules/backend/Ajax.php on line 285


any ideas what could help me solving the Problem?

Hi,

I have the same problem. I didn't upgrade but it's a new installation of contao.

Trying the solution of the first post, some Modules like "Downloads" didn't work anymore.

Doesn't have anybody the same problem or maybe a solution?

just manually upload all files of new version

I fight with this after upgrading from Contao 2.9.1 to 2.10.4 manually
everything else was fine but I also got the json error.

My server has PHP version 5.2.9, however firebug detect a call to a missing function "json_encode".

I have added the function found here:
http://www.stetsenko.net/2009/09/php-js ... ore-5-2-0/
at the bottom of the file "/system/functions.php", it works fine now.

I have no old modules running, only the catalog extension.
It works fine for the moment.
