@docteurfitness thank you for the reminder and my apologies if your initial support ticket was missed. You sent two support tickets (under the same name) and both were answered. There’s no ticket related to the problem (too many JS files) you mentioned. Someone, it wasn’t sent properly, perhaps due to a system error when you sent it, which is very unusual. As it took longer than usual to get back to you here, I’ll extend your plugin license so you can use it for a longer time (until you might decide to renew it) as an apology.
Now, in regards to the problem you mentioned, I strongly believe (I’ve noticed this before, it’s rare, but it happens once in a while) that there’s a non-unique character in one of those single files added to the main combined file, that makes the plugin create a new combined JS file on every page load, thus increasing the number of files and kind of defeating the purpose of using the combine JS feature, which, frankly, is not such a thing anymore, since the HTTP/2 protocol is in use.
Now, can you please use a service such as Dropbox (or any other you may prefer) and add a ZIP file there with the contents of /wp-content/cache/asset-cleanup/? I want to investigate those files. Based on the print screen you sent me, the large one has 260664 bytes. So, for sure, the problem is the one I believe it is ?? We’ll sort it out! What you need to do is exclude the culprit single file from being added to the combination file.
