We had a bug in that security release 126.96.36.199, this new version 188.8.131.52 fixes it.
The 184.108.40.206 we released yesterday was breaking images in wiki pages
when they were called from image gallery (or from a generated source).
Then here is a cleaner 220.127.116.11, with patches against 1.9.7, 18.104.22.168
Thanks to sylvie, niclone and ohertel for helping me in that operation !
