so I went and downloaded the patch - #12 ( I have 7.5.4.2)
Uploaded and overwrote the directories. After flushing cache - How do I verify the patch is functional?
Noticing you have v 7.5.4.2 what is the reference to #12.
Okay I get the #12 now.
If you did not upgrade your version you should have used #10
the #12 patch is for 7.5.6 you need the one for your version.
