We had a bug in that security release 188.8.131.52, this new version 184.108.40.206 fixes it.
The 220.127.116.11 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 18.104.22.168, with patches against 1.9.7, 22.214.171.124
Thanks to sylvie, niclone and ohertel for helping me in that operation !
