Single skin damp issue

Hi there, I have recently purchased a ~1910 end terrace which has had one of its chimney breasts removed. This has been left single skin and I'm unsure what it is filled with, this seems to be allowing water to seep through to other plaster which is now soaking. I believe the rest of the wall is cavity and may have been insulated a long time ago. The other chimney which is still in place also has damp either side, it is capped but not vented at room height, therefore this will be done first. Survey suggested rising damp but id rather avoid going the dpc route first. As for the one which has been removed should I also try to improve ventilation? Or is this a separate issue? I also must comment that in the recent high winds around January time the roof had a gaping hole directly above where the damp is being seen, surely this much damp isn't caused by this though? The roof is now fixed and no further damp is being seen, but it is still soaking. There is also a fair amount of white substance - salts coming from the brickwork presumed? My thought process is to remove what appears to be gypsum plaster, install airbricks, allow to dry for atleast a month and replaster with lime plaster, is this the correct approach or is there other options available?

Many thanks

Get all that crappy wallpaper off as well while you’re at it.
Already done.

For those who are commenting saying its all good, the plaster is soaking. I'm hacking it off today and sticking a dehumidifier in to get it fully dry. Any further advice would be really appreciated

Hack off. Check exterior ground levels. Check under floor, check drains/down pipes etc

As soon as you hack it off, you’ll see it drying out.
