I'm using mediawiki 1.27.1 with php 5.5.21 and 5.5.52-MariaDB, and WikiEditor 0.5.0. I'm using chromium 55.0.2883.87 and Firefox 50.1.0.
Friday I wanted to personnalise my wikiEditor toolbar, so I changed '$wgAllowUserJs' to true in order to allow 'user/common.js' to be working. I put my code into that page, and tried many modifications. At some time, when I wanted to push an image to a button, the wiki didn't allow me to do that with an '400 bad request' error code.
Since then, It's impossible for me to submit anything. If I try to preview a page with 'preview' button that do a POST submit request, I've got the '400 bad request' error.
I deleted my common.js page, disabled '$wgAllowUserJs' variable, check my logs (nothing in there), activated debug mode (nothing there too), tried with Firefox (the error is 'secure connection failed' on this one).
I also tried to lurk in database to see if something went wrong, but I don't know where to look.
I tried with burp to see the request, it doesn't seem to have any issue. My httpd reverse proxy don't print logs in '/var/log/httpd/access.log' for the 'submit' request (no problem for other requests), but log the 408 error reply.
Another interesting thing is that I'm the only user affected by this bug, other users have not this problem..
Does anyone have an idea about to solve my problem or anything to get more logs on this ?
Thank you very much
