Website Crashing After Implementing Plugin

Hello,

I was using your plugin for a while, just to use the normal cache settings. Yesterday, I decided to try implementing your preload settings, which has completely crashed my website.

We host our website on a VPS server, which I now understand could have been part of the problem. Regardless we are receiving a horrendous amount of “traffic” to our server, which seems to be stemming from the WP Super Cache plugin, even though it has since been completely deleted off the website. In result, the website is crashing multiple times a day when these spikes of “traffic” occur. We have never experienced this problem in the history of our business, and no other changes were made to the website environment when the issue began.

When reviewing the website’s FTP, I can see that there is one PHP file named “class-wp-super-cache” still on the backend, which has somehow merged information with that of an unrelated plugin. Otherwise, I cannot see any more proof of the plugin on the FTP, but the website still continues to crash regardless.

While the website has crashed a few times with no apparent cause, the majority of the time the crash seems to take place when opening a preview of a page that I am editing.

Any recommendations you can provide on fixing this issue would be of great help, as the downtime of the website is having a detrimental effect on my business.

I look forward to your response.
