I have had 2 instances so far where shortcode stops displaying on my client's websites that they have ordered and paid quite a bit of money for. What happens is that their shortcode just randomly stops working. Every page on my websites is called to with a shortcode function (ie: [homepage]) so that I can update 1 location in my mu-plugins and it will change them all. What's happening randomly (I mean randomly -- it happened last night then this morning it stopped happening, on 2 sites) is that the [homepage] shortcode will pull the information from the homepage_content.txt file I am using, but the shortcode called to from within that function won't display.
ANOTHER issue (that might be related) is that Cloner keeps throwing an error for me, it will NOT find the new blog in the 'Replace Existing Site' field, it just keeps spinning on the loading animation. When I input the new blogname manually and hit 'CLONE' it will go to the clone screen, however that screen keeps loading but throws an error. After reloading it (even after the error) it appears to have worked fine, the clients website was cloned just fine. But it still told me there was an error.
PLEASE help me - please help me quickly, these clients are throwing a lot of cash at me and I am JUST launched and can't afford to flop with a bug like this. Ahhhhh!!!
