Do I need to apply 512PL3 before applying 512PL4?

[sauloon]

Hi,

I am running 5.1.2 PL2. I did not apply PL3. Now that PL4 is out, do I need to apply PL3 before applying PL4?

regards,

As far as I know PL4 contains all the changes of PL1, PL2 and PL3 plus the new stuff, so you don't need to install PL3 in the first place.

That's normally correct...however, on this occasion I would apply each patch separately, as one of them required a script to be run (which the latest one does not).

Patch 3 isn't available for download anymore, only Patch 4 is.

You only have to upload Patch 4 but you must still follow the instructions that were given for patch 3- https://forum.vbulletin.com/node/4110991
