Hello, Yes we always have the latest version of ATUM installed.
This is a pretty serious issue. Loading the stock manager strains our server resources so much that we get throttled by our host. I am in the process of upgrading our hosting package to accomodate this plug-in which is crazy. There are no other issues on my website that strain my server resources other than the stock manager. It a constant struggle to load it, between time outs and Cloudflare blocking it, 500 errors, 524 errors 504 errors, you name it. ONLY with the stock manager plug-ing and this has been going on for a long time now.
Any help would be appreciated.
