  • Almost 5 years - and it's still just as good

    I've been using Seraphinite Accelerator for almost five years. My knowledge of web technologies is exactly what I need to run my own site, pcminsk.by, but I've always been obsessed with its speed. At one point I tried half a dozen plugins, maybe even more – and only this one gave an obvious, instant boost, without endless tweaking and empty promises. I just turned it on and saw the difference. Since then the plugin has become my benchmark. I recently switched to the full version – and that’s a separate pleasure. The site got even faster, although it felt like there was nowhere left to go. And everything works out of the box, with no magic incantations or complicated workarounds. The main thing is the real performance gain, which I notice, and so do my visitors. Huge thanks to the developers for a product you can use for years and never be disappointed. A truly solid plugin.

  • 500 Merchant

    I have encountered a problem: Google Merchant Center has started rejecting my products, supposedly due to a 500 error, even though my server is very powerful.
