Why is the site origin slider not showing up

I have used SiteOrigin page builder for a few years as it helps segment my content and I can place it without the enormous gaps that WordPress leaves. However, i have have had a catastropic problem I just found on a big ecommerce site I am building. After placing several siteorigin sliders all throughout this huge site that I have been trying to build for a long – long time, all of a sudden, after thier last update probably, all of these sliders decided to just not show up!! I have so many of them throughout this large site that it will take hours upon hours – day after day – week after week to locate all of them and delete them. What worked perfectly before now just does not show up. This is not a problem that either free or paid support can help – unless they offer to log into your site and fix it for free – which is a ridiculous notion. Of course no one is going to do that. I am stuck with either closing the site down or spending endless hours locating each one of these sliders and deleting them – all because a plugin has got a “bug” in it. Instead of a “bug” it is more like a disasterous monster of a problem. So, if you are going to utilize the siteorigin slider – beware! I am afraid to dig into the site and just see what other disasters that await me. I will probably have to just delete the site because I do not want to spend an eternity trying to build a decent site. If I have learned one thing for sure, Worpress is not the CMS one should use to build a large site. It is far too problematic. And everybody wants to create a plugin – which creates more problems in the WordPress CMS function. It’s an endless game of updates – bugs – fixes – and then more of the same – time after time.
