@mseidlinger I “solved” this by short circuiting the log() function with an immediate “return;”
My suspicion is that hosting providers that may have a network filesystem underneath the “uploads” folder (which WordPress does allow relocating) aren’t expecting this may writes, and definitely not low latency writes.
Sounds about right. I work with a lot of sites on Pantheon which does indeed move the uploads folder and has limited writable folders. I do loathe making direct code modifications to plugins, but this may be the only recourse until the plugin developers come out with another update/fix.
