ok found it,
i unpacked the archive and uploaded to /components/com_sh404sef/sef_ext/
refreshed site and i worked
not funny se my digitalcounter with the picture not found in it., lucky they shoved up correct when plugin vere uploaded
I unzipped and uploaded it to root/components/com_sh404sef/sef_ext folder and it didn't work. Should I be able to see it in the back end of sh404sef under the plug in tab? Because it's not there. Would I then change the settings for that component back on e.g. not skip that component?
