I figured out the offending plugin. It was the Leira Letter Avatar plugin, which is also used here.
When I reactivated it, I didn't realized that you had to do a second save within the plugin settings to turn it back on. So when I noticed that a bunch of avatars were missing, I checked and saw I needed to save and turn it on. As soon as I did that, the site got slow again.
So I have turned it off...
Something must have happened recently that has caused a conflict with it on my server. It's too bad since I like that plugin. But I at least found the problem.
What you say is a bit confusing, because you told us that you did disable all plugins and no luck.
Anyways, Leira is something i use also without a single issue. But every site is different.
@dimalifragis Oh i know...
Did that a few days ago and nothing changed. Did it again today and all of a sudden things worked again. Which is why I was so confused.
Strange about Leira plugin... Love that plugin. But I guess it is technically not compatible with my version of WP. Hopefully there is an update on it soon and maybe I can reactivate.
