When editing new article I get http error when uploading images from media-manager. I uploaded via joomlas-manager, inserted image into blog-editor and when trying to save I get a blank browser. The easyblog-configuration is OK.
I don't seem to locate the key file but when I tried accessing the back end and viewed your php info, it looks like the GD library isn't compiled with PHP. You might need to recompile PHP with GD library. If you are using YUM, it should be pretty easy. Just run yum install php-gd .
I've checked your site and seems like the image upload failed is because you have extra '<' in your header http://screencast.com/t/kNHBYGwC . Then I check the plugin to identify which plugin causing this addition '<'. It is caused by PayPlans-Ben-MySQL Query. You might want to consult the developer about this issue. I've turned off the plugin and the uploader is working fine. Hope this helps.
