@Hubzilla Support Forum My shared host provider was "the usual dicks" already:
"it'll be fixed automatically, once CloudLinux builds incorporating those fixes pass stability checks".

So if i apply "session.upload_progess.enabled = Off" now I'll have limited security and probably will need to apply "session.upload_progess.enabled = On" when a fix has been applied, right?

I don't know, if I am still up for running my own sites at all. This stuff gets too nasty among the music making. Anyhow, thanks for any advice.
