Hi, I'm just starting to use my installation and I can upload images via my Smartphone (Google Chrome) browser (non-flash uploader). On my Desktop I'm using the fancy flash uploader and it shows the image uploading (with the percent) but, when it goes to 100% and appears it is finished, it says sends message window "Error: Their was a problem uploading your image" with the filename below.
I saw checked several messages but, still not sure what the fix or issue may be?
I believe that implies it's returning a 406 error, which is "not acceptable". I believe that will be related to mod_security. Your host should have logs that will identify the rule that was triggered. They can add the necessarily whitelist for this. (We have seen this a couple times before, though not for some time.)
