Thank you for helping.
The plugin, Advanced Custom Fields PRO, was the culprit.
Thanks again.
Ok – Here are the steps I followed…. And it is faster. Thank you.
Updated to very latest NextGEN release.
re-activated W3 Total Cache.
And this, I think was the biggie – “clear the image cache under Gallery > Other Options > Miscellaneous then give it some time (and some site refreshes) to rebuild the caches.”
Thank you for your help.
Hi Cais – Thanks for the reply.
I deactivated W3 Total Cache two times to see if it was the culprit. It’s not. Running NextGEN by itself is very slow. I purged the cache via the browser (Chrome) and NextGEN is unusable or close to it. It doesn’t seem like I am the only one with this problem. Any suggestions? Thanks
