I am using LR 6.3. For some reason, all my plug ins have disappeared from LR6. They don't show when you click on Edit in.I have posted about this previously but am still unable to resolve this despite doing the following:
reinstall LR 6 in Yosemite, uninstall, reinstall in El Capitain
Checked permissions in Adobe Library folder
LR6 shows the plug ins Yosemite, Plug ins are visible in LR5 in El Captain, Plug ins are visible in Photoshop CS6 in El Captaine
I looked for Adobe telephone support on this but it seems Adobe doesn't want to have people calling for tech support.
