I have an install of SilverStripe 2.4.0 and have also installed swfupload, dataobjectmanager, and imagegallery. After trying to create a new Image Gallery page I get the following popup window:
<head><title>502 Bad Gateway</title></head>
<center><h1>502 Bad Gateway</h1></center>
I am running SilverStripe on an nginx server. Please note that this is a duplicate question to another already posted in the General Questions forum (http://www.silverstripe.org/general-questions/show/279081#post279081), but since I am not the owner of the thread I can't move it to this forum where I believe it belongs.
I found a fix for this problem at this [url=http://blog.rackcorp.com/?p=14]page[/url] on the Rackcorp site. It has to do with increasing the fastcgi buffer size in the fastcgi_params file with nginx. However, now I am curious how big the buffer is when coming from a page created with the Image Gallery module. Finding out that information is beyond me, and if possible, I would like to ensure that my buffers are not overly large in my configuration.
To summarize the Rackcorp article, just add the following lines to your fastcgi_params file and restart nginx.
Well, I played around with the entries trying out values and came up with the following shorter list of configuration entry values that are much smaller than the Rackcorp values and still work. If anyone is familiar with nginx and can tell me if these are reasonable it would be great.
thanks for your post, i had same problem with nginx with silverstripe.. your quick fix saved my day..
Looks like the default nginx setting wont allow big respond header with quite big content using ajax call.
