First off all, thank you for great CMS/CMF, I think the best out there according to my preferences.
I have some issues while using image field type for uploading. I'm receiving 403 Forbidden, You don't have permission to access /processwire/backend/page/edit/ on this server.
Screenshot with firebug visualization:
I found some topics here (#1, #2), but none of them solve my issue.
phpinfo() does not indicate there is mod_security installed.
It also looks like getPhpFilesAjax from wire/core/WireUpload.php never executes and error pops somewhere before that.
It looks like this could be some hosthing restriction but I don't know what kind and how to address this problem to their support.
Can you please point me somwhere?
