Hello,
clearly you can agree with me that asking for website and FTP credentials is not a common way of providing assistance for troubleshooting, or at least it’s odd if you consider how competitors and players of your same industry are doing that 🙂
But aside from this, I kindly asked to not apply changes and the first thing you did was adding WP FileManager without my consent. Then access to FTP was provided and after doing some troubleshooting activity you disappear without leaving a message as status update. One could find it not really professional. But I don’t want to argue, it is what it is.

Now for the technicalities: I thought that local cache (page cache/Html cache) could be the issue, but in fact I am not using that. Autoptimize is just minifying CSS and js while leaving the page content intact.

– Is that any js or other library or dependency that your widget does use?
– Do you have a test php code that I can put in your widget to produce a verbose log?
– Can you explain the widget logic? Maybe there’s something wrong with that: are you checking posts with comments or just the ones with views?

Thanks, I’ll conduct further testing with plugins in the meantime,
AP
