when I try to add a photo to my wall all I get is a white blinking line at the top of the page
what can be the cause?
Please check your firebug console in the Firefox browser, there should some error. I believe it is the same as here: http://www.oxwall.org/forum/topic/30611?page=1#post-129205
Follow this tutorial: https://docs.oxwall.org/faq:parse-error-troubleshooting
Also Forbidden. Which means there's a mod_security module enabled on your server. Contact your hosting provider to disable it or configure it properly.
