Shortcodes ultimate not working

Hello! I have two websites in which I’ve installed Shortcodes Ultimate (both websites have been migrated from another host service recently). One of them works perfectly fine. In the other one, whenever I insert a code editing any of the URLs, as I check the preview in chrome I see the shortcode text (for example, I see [su_heading size=”16″ align=”left” margin=”30″]asdccxz[/su_heading] in the website, instead of the actual heading).
I’ve tried to uninstall and reinstall but I still have this issue, plus, I see what I previously wrote (the “asdccxz” I wrote to try it out) as if there was some sort of cache information even though I’ve just installed it.
Any ideas? Anyone had the same issue? Thanks!!
