I have a problem with a plugin added to my AcmeBlog theme. I reached WordPress and they think it’s related to the theme and you can solve the problem: My Photo Gallery by Supsystic disappeared from the plugins menu, the gallery of the webpage only appears as a code line (text).
I tried to reinstall the plugin, but I got a message as if it already exists. However, I can not see it, not even to erase it.
I have the same plugin in another website with another theme. It works normally there.
