Hello, unfortunately it did not work. Reaching out to rank math, maybe it is not WAF, I assue that this would let SEO anaylzer work.

I see that you posted this question in several different plugin forums. When I use Google Chrome Developer tools to view your site it looks like the problem is related to WooCommerce caching. In general it looks like you are using several plugins that do the same thing > more is not better. If you use several plugins that do the same thing then you need to make sure they do not conflict with each other. ie if you use 3 caching plugins you are going to have regular problems. You can use 3 caching plugins, but you need to choose which caching plugin is going to handle something and turn off that capability in the other caching plugins. Same applies to all other plugin types: security, SEO, etc. etc. A good example is having 2 people drive a car at the same time = not going to work out well.

I cannot tell exactly what is going on, but it looks like you might be minifying js and css scripts. NEVER FOR ANY REASON use js minification. What I would do if this was my site would be to turn off caching in all your caching plugins and flush/delete all cache and then just enable Cloudflare cache after flushing/clearing all Cloudflare cache. At this point it looks like WooCommerce is caching things, WP Super Cache is caching things, Cloudflare is caching things and maybe even your Nex theme.

Usually when you see these types of errors you have a caching problem.
